Here's another one: when somebody stands too close behind you in line. It's even worse when they are so close they are breathing on you. You try to move to the side, but then they follow you step by step so they are breathing on you the whole time.
I don't remember what I was trying to say. My portable computer has an auto-complete function that fills in the wrong words sometimes. What sometimes happens is this: I was sitting at the counter at a café writing, and somebody sat next to me who could not settle. He was sitting in a way that was encroaching on my personal space. He was beside me but partly facing and leanign too close toward me in a way that was looming . He was fidgetting and constantly doing anxious things with his hands. He kept moving his legs around. He looked like he needed to go outside and run off his hyperactivity. It turned out that he was waiting to for a friend who worked there to do somethign for him.
