You Know When...

You know when you see someone from a few years ago and you decide to try and make eye contact? But then they don't remember you so now you're staring at this person who has no idea who you are? Then you have this other issue where they see you staring and slowly try to move side to side to see if you are looking directly at them or something over their shoulder? Now you have to try and act like something over their shoulder is super interesting and in the split second that they are turned around to see what you were looking at, you start walking the other way? Cause same.
