Equal chance of visiting three bars, police couldn't find him

A family member used probabilistic thinking to describe their partner's drinking behavior: going out 90% of the days, randomly visiting three regular bars. After police failed to locate them twice, the family member applied Bayes' theorem to deduce "where he actually is," realizing that alcohol issues don't just drain emotions but persistently erode life's logical foundations.

90% of Days, He Was Out Drinking

It took me a long time to figure out his drinking pattern. Not every day, but roughly 90% of the time, he would go out. The remaining 10%, he stayed home—usually because he felt unwell or had drunk too much the previous day.

His drinking spots weren't random. He frequented three bars, all nearby. At first, I thought he chose based on mood, but later realized it wasn't that—he selected them with equal probability. Each bar had about a 30% chance, leaving 10% for staying home. The entire sample space was divided into four clear probabilities.

This discovery struck me as both absurd and heartbreaking. A man with no planning in life had achieved such precise randomness when it came to drinking.

The Police Checked Two Bars and Didn't Find Him

Once, he didn't come home at night and wouldn't answer his phone. I called the police. They checked two of his usual bars but couldn't find him. The officers told me both bartenders claimed he hadn't been there.

A question popped into my head: Was he actually at the third bar?

Most people would say, "Of course—that's the remaining 90% probability." But I knew it wasn't that simple. The police hadn't deliberately avoided the third bar; they'd genuinely searched and found nothing. This meant he might not have gone out at all.

I tried applying Bayes' theorem. If he was at the third bar, the probability of the police not finding him was 100%—since the other two bars were empty. But if he wasn't there, the probability dropped to 1/7, because only the 10% home scenario would explain both bars coming up blank.

The posterior probability of him being at the third bar was far below 90%. He was more likely at home or somewhere else entirely.

I recalculated this multiple times. Not because I'm good at math, but because it hit me: His drinking had warped our family's judgment. Even locating him required probability games.

The Hardest Part Is Never Knowing When It'll Happen Next

Many assume the worst part is seeing him drunk. It's not. The real torture is the uncertainty—not knowing if he'll drink today, when he'll return, or whether this time will end in disaster.

His pattern seemed predictable—90% outings, three bars chosen randomly—but this very predictability became the torment. You know it'll likely happen, yet can never pinpoint which day or which bar. You just wait.

While waiting, you replay memories: When was he last drunk? Last crisis? Last promise to quit? Then you realize you've lost count—the timeline is a tangled mess.

I tried everything: pre-outing talks, hiding alcohol, silent treatments. Nothing worked. His behavior wasn't emotion-driven but propelled by some incomprehensible inertia. Like that probability model, he drank not because he wanted to, but because "it was time to go."

Family Logic Erodes Piece by Piece

His drinking didn't just affect him. It rewrote our family's operating system.

Dinner used to be at a set time. Then it became "wait for him"—except by 8 or 9 PM, with the child crying from hunger, we'd give up. Eventually, we stopped waiting. Yet that suspended anticipation lingered in the air.

I began scheduling life probabilistically: If he had a 90% chance of drinking out, I wouldn't cook for him. A 30% chance at Bar X? I'd avoid that route. 10% chance he'd stay home? I'd make myself scarce to dodge the awkwardness.

On the surface, life continued. But everyone was tip-toeing around invisible landmines. You never knew when one would detonate, but they were always there.

Our child once asked, "Will Dad come home today?" I didn't know how to answer. "Probably" was too abstract. "I don't know" would frighten them. So I said, "Let's wait and see."

"Wait and see" became our household's mantra.

When "Normal" Becomes a Luxury

Once, he stayed sober for three straight days. I felt uneasy. Was he sick? In trouble? Turned out the bars were temporarily closed.

That's when I realized he'd redefined my "normal." A sober day felt abnormal, while drunkenness was the baseline.

This distortion built gradually—through every "let it slide today," every "he promised to stop, maybe this time," every "the child needs a father" justification.

But how long could this last? I only knew that continuing would turn our home into a probability puzzle—everyone guessing his next move while he himself remained clueless.

Eventually, I reached out to support groups. Not because he had an epiphany, but because I was breaking. I needed guidance—not for him, but for myself and our child.

If you're in a similar place, remember: You don't have to calculate every probability alone. Pause. See what you can do for yourself. Even replacing "wait and see" with "I'll take care of me first" is a start.
