So I don't know if I'm being a bit uptight here.
A friend sometimes - like, once a year - catsits when we're away. We were away last weekend and she did so then, and we get notifications when people are at the door as we've ring cameras. We can see that over three nights she had two people to stay - not people we know well, I recognised one as a girl we know and another as her brother. It's fine but she never said a thing about other people staying in our house. She's quite an elusive, secretive character - big high flier in London who does drugs with lots of people (but also holds down a hugely responsible job somehow).
Is it ok to have people stay over and not say anything in these circumstances?
AIBU?
