I laughed and chose not to disturb him.
I was happy when you did that and was feeling cheerful.
You were feeling happy and cheerful? What prompted that?
Because, you did the right thing in leaving him alone. Some people just don't want to be bothered at certain times and you respected that.
I was like, fuck that guy.
Do not feel bad for not wanting to be disturbed at times. This is what you need at different points in time if you truly want to be able to get things done?
