I mean I don't own a towel that covers my body. So Buddy has to kind of just…witness that.  She's publicly in denial about the source of her physical ailments. Yet at the same time she realizes that she's so gross that she actually feels sorry for her roommate because he had to see her naked. Seriously, when have you heard of a woman feeling sorry for a guy because he saw her naked? No normal human feels this way. She feels this way because, deep down, she knows she's disgusting and everything else is just a (really) huge facade.
