Kind of stolen from theofficialnoodle but I can relate so..
Having an awkward interaction with someone, knowing something awkward will happen, or just not wanting to talk to someone because I'm an antisocial piece of garbo so I walk around the whole building just to avoid someone even if they are a hallway away or something.
My brain immediately goes, "Shoot, I saw them there a minute ago so they could come out of any of these three hallways... Welp time to go back the other direction, down three flights of stairs, take three rights, go back up the stairs and be in the hallway I could've been in 10 years ago if I wasn't antisocial"
