I'm going to a jr. high dance and most of the girls dance with boys. I'm afraid no boys will ask me to dance and then i'll be the only one without a dance partner. Do u no anyways I can get a boy to ask me to dance without directly asking them?Do u no how to get a boy to ask me to dance with him?
No offense to guys, but sometimes they don't get the hints. :) If you're by a guy you like or a friend -guy just say, ';I love this song, wanna dance?'; It needs to be direct so they don't just say ';Yeah.'; And say it in a friendly way, not in a desperate way.
