Do you ever see people you are pretty sure you know (know like they went to college with you but you exchanged exactly zero words) but you aren't actually sure if it's them so you don't want to say anything, but keep giving them strange looks instead and look like a freak? Also it's really hard to take a picture of yourself when like 20 people are sitting behind you and you don't want any of them to realize you are taking a picture of yourself.
