So my mother-in-law always brings her own towels (to save on washing...) when she comes to stay.
But AIBU to be irritated that she leaves her hand towel in the bathroom until the second she leaves so she never has to use mine?! My hand towels aren’t perfectly clean (I always put a fresh one out for her as now I feel paranoid) and I don’t have any diseases.
Trying to remain zen about it but feeling rather insulted!
