I think your questions should be "Why do girls like to make boys wait for them?" If this is the question, here is my answer: "Because the girls are smart." :)

Ah!?... what what...? I encourage you to be more specific here ! ^.^

well,if you mean why girls wait for a guy who went in another country or so ..the answer is they don't like it ! but when we put our soul into a relationship we can make things that we didn't knew we coul...like long waiting..........but wait,cause not all girls do it !:P
