Let's see. You're a bunch of frat guys having a typical party and some lunatic crashes through the front door demanding to know who is throwing an underage drinking party. I'm sure the universal response would be to direct the disturbed fellow to the fraternity president who would debate him regarding the pros and cons of underage drinking. After realizing the error of his ways, the president would immediately halt the party, chastising his brothers for their boorish behavior. He would then have several brothers escort the father and his two daughters 35 miles to their home in Manchester. Once there, the frat brothers would drape their coats over any puddles so the girls could get into the house without getting their feet wet and then serenade the young ladies with a rousing chorus of "A Bicycle Built for Two"
Okay. You have made it clear. You are more concerned with your ability to drink and hang with your buds then care a whit about two young girls.
