Had a roomate who didn’t want to wash dishes, so she piled them up under her bed. She also refused to remover personal hygiene products from her undergarments before washing and drying them…. and I often found the laundered product left in the dryer.
Another roommate (it’s now ten years later and I hope she reads this blog), was a horrible pig. She showered infrenquently, “borrowed” my clothing without asking and “forgot” to return said items, and when her cat vomited on the carpet, she’d wipe the top detritus from the carpet, but would never use water or cleaner to get the acid and bile out of the fiber. The carpet had a crusty texture as a result. She was a convert to Judasim and would leave candles burning and go to sleep, claiming that letting the candle burn was required for Shabbat (I have yet to read any documentation about the “risk your home and life and go to sleep with the candle burning” decree) . Ironic that bathing is also part of the ritual, but was usually excluded.
