when I was living in dorms they had tours for high school seniors that might come next year, and they;d check out the halls and the rooms. One time I come back from shower strapped with a towel and bucket of soap/deodorant and my roomate has let liek 15 kids into our room.
So I come in and stand there half naked expecting the RA dude to quickly exit the kiddies btu he just keeps giving his little speech, so after like a minute of confusion/embarrassment I say "hey, uh get the **** out, yeah?" and I get written up..
but you can't get written up at your house, so just tell them, get the **** out, yeah?
