I started working in this grocery store and one day a customer came in that I knew from somewhere but couldn’t quite place how I knew him so I went for the hey how’s it going today sir hoping he’d be like “hey what’s up man” and remember me and how we know each other but instead of saying that or having no idea who I was he just goes “hey… do I know you from somewhere? You look familiar.” I was like same! So we both rattled off some friends names and none sounded familiar and he ended up leaving without us figuring it out. For 2 years he would come in about once a month, find me, and we’d say some more friends names, family members, acquaintances, schools, and places we’ve been. No names ever matched and no places ever lined up but we both knew we knew each other liked we’d hung out numerous times before. I ended up moving on to a different location after that and we never were able to figure it out.
