This thread reminded me to watch the bedsheets and towels today, thanks.
I used to live with a hippie boyfriend who would use my bath towel, for no reason that I can tell-- no shortage of towels, and it wasn't any closer to the shower. When asked, he would just say "Why do you care?" Well, because if I'm going to dry my face on something that has also dried someone's ass, it should at least be
my ass. That apparently did not sink in.
Current anarcho-capitalist boyfriend respects my property rights.
