Expectations

I don't ask a whole lot of my suitemates. If they don't leave their crap all over the bathroom, and clean when it's their turn, then I am reasonably happy with them, and do not feel the need to complain. Of course, I have complained about them before. However, tonight's complaint is much, much more serious.
Do you think it is reasonable to expect that when you are showering, your suitemates' boyfriend(s) not walk in on you? 'Cause I certainly do.
What on earth makes a guy think that, in a dorm which is clearly not co-ed by rooms, he can just walk brazenly into a bathroom where someone is showering?? Obviously, said person will be a girl, and more than likely, said person will be just a tad bit offended that the guy even decided it was ok to open the door and peek in, let alone go right ahead and drop his pants to use the toilet! You'd think that would be obvious. But no. In fact if, when, after stepping out of the shower and covering herself, the offended girl were to slam the door- which this lovely, considerate boy had left open after entering, peeing, and exiting- the guy's girlfriend might feel the need to say something along the lines of "rawr!".
I really have to talk to these people. If they don't understand reason, for example: KEEP THE BLEEDING DOOR SHUT WHEN OTHER PEOPLE ARE SHOWERING YOU INCONSIDERATE TWIT!, then perhaps more drastic measures will have to be implemented. This could be the fourth Home Alone movie in the making. Only time will tell...
over 'n out,
