I think that coming into a girl's HOUSE and thinking she is disrespectful for telling you to be quiet is just WRONG!!! This may be your sorority, but this is NOT your HOUSE!! I would never go into someone's house and not respect their wishes like that. How tacky and rude.
And really now, if you like a girl enough to extend her a bid, I would hope that you respect her enough to treat her like a human being and not that has to prove something to you. She may be your sister someday.
