My dorm toilets are picky. They'll take a massive load of crap, but if I need to flush a tampon, suddenly they can't handle it. It's a freakin' tampon.
It must be a man's toilet.
So now I have to throw my used tampons in my trashcan, which is pretty gross for any visitors I might have. (actually, i never have visitors, so it's all good) And it's annoying to be ready to answer the call of nature and suddenly having to scurry into my room with my pants around my ankles, to drag the trashcan back to my bathroom praying I don't drip, just to throw away a tampon.
Fortunately, I only have to go through this once a month. But I can't wait until I get a house with a toilet that isn't a pansy.
