Ah, yes. I understand, I am stuck with a roommate right now who isn't very clean. So I do a lot of handwashing and only dry my hands with a towel I keep in my room so she won't contaminate it. I often have to re-wash dishes she washed, too.. because she doesn't wash them properly and there's like still grease marks and sticky stuff on them. My family is pretty clean though, so when I stay at my parent's place I feel it is safe (they haven't caught any sv* since we were kids).
