what are you really afraid of? It's not really like the rejection will affect your self esteem because you don't have any and that's why you won't talk to them in the first place. Only good can come from it. If she reject you, you stay the same, if she accepts and gives you a number, you feel a helluva lot better. Remember, girls are exactly the same as guys except they are more attractive and have breasts and a vagina...what I'm trying to get at is they are just as "scared" to talk to a guy as you are to talk to them. Then there are people who grow past the age of 10 and have no problem talking to the opposite sex.
