Got a family member staying with me who I stupidly said could stay for 3 weeks whilst she waits for her tenancy to start. Didn't realise how irritating another adult can be. Eating my food without asking (OK it's just a couple of tins of soup and my home made bread but still), damaging my stuff (using a scourer on my pans which has scratched them up), using the wrong bins for recycling and food waste, putting the heating on when I'm out (I know this because I can see the timer setting has changed). I keep telling myself it's just for another couple of weeks but I'm totally baffled that a 30 year old can be so inconsiderate and incompetent. I'd like to approach her about it but not sure how without making it incredibly awkward. How do adults live on their own for years but still end up being so useless and inconsiderate? Yes I know I'm going to be flamed for not laying down the ground rules but I'm willing to have to conversation. My anxiety gets in the way.
