he buys used panties...? what? of course hes stealing your girls panties....

anyway, you should get a maid to come clean his room and do his laundry once a week and up his rent to cover the cost....

you also should ask if he ever intends on getting laid and suggest taking some pride in himself by means of a shower and tidying up his surroundings. I agree that he is probably depressed, doesn't sound like he's having a great time....or by him a whore that will also clean up after him...up the rent to cover the cost...hehehe...that sucks.
