I kicked everyone out so I could enjoy my chair in peace. Was I in the wrong?
Why did you kick everybody out?
People bother me when they're in the room.
Sometimes people just want to be alone and that is okay. You don't have to spend time with people if it is stressing you out. As long as you are polite people will understand.
I don't care, the chair is mine and I won't let anyone take it.
You should be more gentle with people and stop being so crass about it but you should be allowed some alone time.
