I recently went away for a few weeks and a friend of mine and her partner stayed at the house to give my cat his daily medication he needs. Friend always likes to stay over as she lives in a small single bed flat with her partner and I live in a 3 bed house with garden so she says it’s like staying in a nice air bnb for a while. While it’s a nice favour that she looks after the cat, I returned to find that my car keys weren’t where I left them. I asked her about this and she said she used the car for a friend to give her some driving lessons in. This was never discusses and I also found the tank to be almost empty considering I left it with half a tank. I also found out from another friend that she hosted small get together a with friends. Though nothing was broken or got out of hand, I can’t help feel that it’s taking the piss a little. All my bath bombs I got in a set for my birthday were used and she had also forgot to take the recycling out for three weeks and the bin was overflowing, resulting in an awful smell when we came home. Should I say something? Or do I just ask someone else next time and not mention it? Or am I just being fussy and should I just be thankful for the help.
