Sehath walked out of my place close to 2 PM that Saturday. We’d stayed awake all night, those nights when you forget about sleeping and random videos seem deep by 4 AM. He only slept for four hours before he said it was time to go back.

Drive carefully, I called out as I approached the door.

Ten minutes passed when the phone started ringing. His tone carried a tremor I hadn't noticed ever.

"I just got in an accident."

The crash took place near the Fireside Norterra Community Center, turning left into oncoming lanes. Sehath rolled up tired, spotted an opening, then made the move, only he started turning way too soon. Got the spacing wrong. For three quick seconds, things looked blurry, till a Toyota slammed into the side of his Civic, steel smashing into steel.

He seemed fine, no cuts or bruises, only shaky. Yet hearing him on the line, voice cracking as he kept saying, "I thought I had time," made drunk driving shift from some old lesson in school to a cold emptiness inside me, knowing I’d allowed my buddy to go home dead tired, unable to handle an ordinary turn.

Twenty hours of no sleep feels like drinking enough to fail a DUI test in Arizona. Sehath wasn’t up quite that long, yet only four hours’ rest after staying awake all night did the trick. It blurred how far things were, made the opening in cars seem wider than real, and got him thinking he could pull off a move he had zero chance at.

No booze. No substances. Yet tiredness, oddly enough, seems lighter, not quite true. Still, the scratched steel said otherwise. Same with the ticket for not giving way, the insurance mess, the panic in his tone when he phoned.

My guilt faded, just like that.

I’ve gone over that Saturday again and again. He heads toward his car, keys swinging, looking wiped out. Me? I just mutter 'be careful', like some phrase could fix what I let happen, watching him climb in while dead on his feet.

Back then, driver’s ed missed the real point: knowing stuff ain’t the same as understanding it. Half a year before that day, Sehath had to attend a mandatory class ’cause we were busted going too fast. The course dumped numbers on him, like how texting while driving spikes crash odds by 23x, or tired drivers cause over 100K wrecks each year, plus reflexes get scary sluggish when you're wiped out. But none of that mattered; I already knew every bit. Yet understanding it never stopped me when Sehath walked away. That awareness just failed to link 'we were awake way past midnight' with 'him getting behind the wheel was a bad idea.'

The confusion around what counts as impaired goes way below the surface. Instead of just thinking about someone stumbling or barely able to talk after drinking, consider this: it’s also quiet stuff you don't see. Take my neighbor, it's said that she takes her doctor-prescribed anti-anxiety pill during break, then gets behind the wheel by mid-afternoon, totally unaware that the small print warns against operating a sedan like hers. The youngster lit up earlier, now walking around like nothing’s wrong, yet THC messes with judging distances way past the buzz. A uni student heads back late, veering slightly across lines out on a country lane.

She’s walking out as morning hits. I’m just standing there, watching her leave.

Life in Arizona means dealing with risks all around. Roads here are tough on errors, wide six-lane streets moving fast at 50 mph, freeways humming near 80, busy crossings such as Fireside Norterra, where weekend traffic surges through at 45, counting on others turning left to make smart calls.

Sehath hadn't.

I stopped by later that day. His Civic could still run, just had a few dents, plus the paint on the right side was chipped away. The Toyota? It wanted a fresh bumper.

"I saw the car," he told me. "I thought I had time."

That’s how tiredness sneaks up on you. Not with a warning, just slow shifts in thinking. It tricks you into feeling sharp while blurring distances, so the car ahead seems more distant than it really is.

"I should've made you stay," I said.

Still, could we’ve seen it coming? We’re just eighteen. The brain’s decision-making part isn’t done growing till age twenty-five, so we’re behind the wheel with circuits still under construction. This explains why Arizona bans alcohol for young drivers. It’s not harsh; it’s understanding that teenage minds aren’t ready for quick life-or-death calls on the road.

Throw tiredness into unfinished growth, then see what shows up at Fireside Norterra.

These days, I’m the one who won’t let you go. If folks head out past midnight, I watch closely, tired eyes, slow steps. One person sighs, then yawns again. My couch is already ready. Last week, Anish insisted on driving home after zero sleep. No debate, I grabbed his keys, dialed a ride, and didn’t care what he said.

Besides, Sehath figured he was doing okay.

I’ve gotten hooked on how hidden disabilities can seem totally fine from the outside, acting like everything’s under control while things are actually falling apart. Medicines swallowed without even checking what they do or warn about. Edibles eaten ages back are still messing with focus and reflexes. Phone pings slicing through attention, glancing at a message for half a dozen heartbeats? That’s rolling blind down a whole football pitch going highway speed.

My dad explained defensive driving like this: expect others to make dumb moves. Back then, I figured he was being harsh. Turns out, he was just honest. Trouble shows up quietly, without warning. Maybe it’s a teen stepping out after hanging out, wiped out, unable to gauge a turn properly, not old enough to realize "okay" doesn’t mean "alert."

The cop said Sehath got off easy, because the Toyota wasn’t speeding more, since he had his belt on, given that no one ended up injured. Like chance is some kind of plan.

Yet fortune fades. Sehath nearly crashed right there, where I go every day, where tire scars remain on the pavement, a spot that squeezes my ribs since I saw him head into it, dead tired, moving way too slow to stay clear.

Each time I start my car today, I’m committing to others on the road, moms taking children to class, bikers riding tight edges, people stepping across crosswalks when the signal changes. This vow means everything. It’s the silent deal we accept when entering highways, moving through crossings, using Arizona’s open stretches between towns.

Sehath tore up the agreement. Not on purpose, just worn out, yet exhaustion seemed fine back then. He left feeling rattled, though no injuries stuck around this round. The person driving the Toyota? Fuming when he stepped out, still in one piece this go-around.

I allowed him to shatter things by staying quiet; when I ought to talk, I didn’t.

I’d never pick that option once more.
