We arrived home from holiday last night. BIL has kindly been cat-sitting for us, popping in twice a day, but not sleeping here overnight. This is important.
This afternoon, I've been sorting out a few things in our room. The sun was shining in, and as it hit the mirror I could clearly see strange marks - handprints, quite high up, and what I think is a willy mark at hip height. They are quite noticeable, so I'm sure they weren't here before we went away.
I suspect BIL has been entertaining himself in our bedroom, either alone or with a partner. He's single and the thought of him bringing a hook-up into our bedroom makes me feel ill.
I've changed the sheets (just in case his activities culminated in our bed), but I don't know if I can bear the thought of him cat-sitting for us again if he does this. But DH will think it's strange if we don't have him back, and DCat has never been to a cattery.
Is there a way I can subtley dissuade him from using our home in this way, without offending him?
I've added photos, but they aren't very good because my phone doesn't seem to focus on the mirror surface.
