I decided to bite my lip just now and make a crazy face. Just to see if I could do it. Nothing stopped me. I don't have a propensity for biting my lip randomly. I just did it. Did you mind control me into biting my lip instead of rolling around on the floor?
I don't know about you but my every moment is a battle between what I need to do, what I want to do, and what I can put off until later. I wanted to cut my grass. I had the ability and the opportunity to do it. Instead, I decided to laze around all day. It was my option. On another day, you couldn't stop me from doing it. Now, I'm thinking about paying somebody to do it. Even I don't know which one I'll go with. Depends on my mood, I guess. Depends on if I have the will to do it.
