When person X is in other people's homes they read out personal letters and snooped into their private affairs, which they then gossiped about.
Recently they house sat and used the other person's printer wirelessly and all kinds of other things without permission. They also boasted how they did not keep the rules set for them or care for the family pets in the way they were instructed to do (putting them in danger)
I am rubbish at setting boundaries, though to be fair this person tries to trample any boundaries anyone sets. I have realised I cannot trust them and feel I want to say something, even though I know I will be slandered and smeared for it. I am struggling with them as "everything is about them" and they constantly are the centre of drama's they create. AIBU to say something blunt?
