I don't really "care" what people say they are going to do, just what they do. If I ask someone to do something and they say "yes" and don't do it then I keep reminding them until they do. Otherwise, someone saying they'll give me something or do something (like call me, take me to lunch, etc.) is what they want to do and they can do/not do whatever they like, it's not about me. I have enough trouble figuring out what I want and think I should be doing.
