I'll take 12 hours to think about replying. "Just informing you" because I thought I said something wrong or I would think they were thinking I was bragging about something. 

Sometimes I'll go into a room and just think of the personalities of people around me. Simulate every possible thing that can happen so I can react in the most optimal way to make them like me.

When I post something on Reddit I'm afraid someone will somehow figure out who I am out of 7 billion people... A more plausible one is that someone irl will see my Reddit account, stalk and judge me. 

I don't show emotions because I'm afraid people will take advantage of me or make fun of me.
