The airport smelled like burnt coffee and recycled air, the kind of atmosphere that makes every goodbye feel both urgent and forgettable at the same time. I stood there holding my son’s hand, watching my husband disappear into the security line with his perfectly packed carry-on and his perfectly pressed suit, and I told myself this was just another Thursday. Another business trip. Another three days of single-parenting and microwaved dinners and bedtime stories read in the voice I use when I’m trying not to fall asleep mid-sentence.

Airport goodbyes are supposed to be simple, predictable even. A quick kiss that tastes like the mint gum he always chews before flights. A reminder about taking out the trash on collection day. “Text me when you land,” delivered in that tone that’s half concern, half going-through-the-motions. And then you drive home through traffic that feels thicker than it should, and you slide right back into the routine that fills the space where another person used to be.

That’s what I thought I was doing at Hartsfield-Jackson Atlanta International—navigating one more ordinary departure under fluorescent lights that make everyone look vaguely ill, surrounded by the symphony of rolling suitcases and boarding announcements and tired faces checking phones for gate changes. My husband looked flawless in that way some people seem to practice until it becomes effortless: crisp charcoal suit that probably cost more than my car payment, calm smile that revealed nothing, black carry-on positioned at his side like a loyal companion, already half-gone even though he was still standing right in front of me.

“Chicago. Three days tops,” he said, kissing my forehead with the mechanical precision of someone following a script they’d memorized years ago. “Conference starts tomorrow morning. I’ll try to call after the keynote.”

“Drive safe,” I started to say, then caught myself. “Fly safe. Sorry. Long day.”
