Paul isn't the best at cleaning, but I don't understand why he's been wearing the same shirt for two weeks. He has plenty of shirts to wear, and he's been washing quite often lately. Leora might have time to masturbate one evening, but even when Paul sleeps or is away for an hour or two, she doesn't do anything.
