so you want to make a girlfriend. there is no guaranteed way, but since you seem to be a bit shy, i will be glad to give you a few tips.
work on your confidence, practice it, try to look your best, also, because this will attract the attention of girls.
try to work up the nerve to talk to them, too, make an impression, it's not very hard if you work at it, and ask for their phone number. be sure to ask them if you can give them a call sometime. compliment them, and if you see a girl looking at you, then look away quickly, go up and start a conversation with her. put in a little effort, we like it :)
