Adult DS 25 still lives at home. DH and I go away every weekend in our caravan and so his newish GF 26 and also still lives at home (who I have yet to meet in person) comes and stays with him which I'm absolutely fine with she lives 3hr drive away. The last 2 weeks we've come home and she's left used panty liners both in the bathroom bin and in DS's wastepaper bin in bedroom.
I don't know how to broach it with him. He will take it that I don't like her without meeting her etc. It's not like she's a young kid at 26, personally I would either empty both bins before I left or pop them in my wash bag to take home with me. I left the caddy bags out as a hint this weekend. I would be mortified to think someone else would see something so intimate and for context they're not wrapped back up in their packet either.
Opinions?
