Why do women do this? Part 2

I'm dealing with a situation like this right now. He calls me up asking what I'm doing and if I want to do something. Sometimes I'm tired and really don't feel up to it. Nothing personal. But he won't take no for an answer sometimes. He'll pester and pester me, like I'm going to just change my answer. Yesterday I was at LSU all day getting stuff ready for the fall and came back to Metairie. Then I had to go help my mom clean up after a banquet she had at her job. He wanted to go out but I wasn't up for it. He got kinda mad, but I just wanted to take a shower and go to sleep.
