Dilemma

I am annoyed that the 25 year old calls me and wants to spontaneously do things all the time. I have a life and I do make plans. I don't feel like I should drop what I'm doing just to go on a walk or to the driving range or a movie with this guy. If he was seriously interested in me (and he has made the comment that he isn't), he would schedule something in advance. So, why do I put up with the last minute games. It seems like such a waste of my time. I guess my alternative is reading or watching television, so I go along with him. But, still. I need someone who respects my time more.
