I really hate it when you are expecting someone to call, but they never call. This is especially painful when the person you expect to call is a girl. I don't know if they didn't call because they never want to talk to you or for some other legitimate reason. This problem is especially present in the early stages of association with a person. I want to be persistent, but I do not want to come across as a stalker.
In a non-related item I just cannot figure out how to use comma and other punctuation. I think I am a reasonably intelligent person but punctuation is incredibly hard. Perhaps, there is no hope.
