I haven't bought drier sheets since I moved in 4 months ago. My roommate runs the drier everyday and you can use the sheets more than once. There are always used drier sheets on top of the drier.
I once found ANTS in the dishwasher. Disgusting? Yes, foul play!
I sort mail for about 6 people. Only 3 live here and only 2 get mail.
Vacuum? They didn't own one until I moved in.
Two months ago I threw out a 70s suitcase with a hole in it- from the garage, and nobody even noticed.
Just last week, the non-slovenly roommate and I realized we were the only ones who ever do the dishes-- EVER!
Did I mention our garage has a door to a dirt cave? No crime scene...Its a condo on a hillside.
