I had someone walk in to my work one day and call my name. I turned and greeted the customer and asked what I could do for them. They confirmed my name again, which they had correct, and then said "you went to XHS right?" Confirmed my graduation year even. "Uh, yeah... That's right?" I said with a confused look on my face.

I just stood there befuddled. I stared at this dudes face for seemingly an eternity. No recognition. I couldn't figure it out. For some reason, he didn't say his name and I was so flabbergasted that someone who lived 4 states away, that I apparently went to school with, happened to be on vacation in MY town and walked into MY store... that I didn't even ask. I was super busy, and suddenly confronted with utter confusion, just frozen. And this dude's just like, "well, see ya" and I have NO FUCKING CLUE WHO HE WAS. It's an interaction that haunts me still.
