["I've asked my roommate to keep the smell contained but it still smells strong as we have a smaller 3 bedroom house. Part of the problems is his bed linen and clothes are always dirty.", 'Have you talked to him about being a bit cleaner in general?', 'Good point and yes we both have asked him to tidy his room up some to help with the bad smells. He works in a deli and does nothing when he gets home, so talking to him did not work even though he agreed to try.']
Ah that's a tough situation. Maybe some subtle hints would work best, like leaving a deodorizer near his room.
My roommate recently started smoking marijuana and keeps it in my girlfriend's home now. It reeks in the hall and aggravates me in my office as well.
