As some of you may be aware due to a long thread I posted a while back, I have quite a few problems with my mum. She just doesn't behave like a normal, reasonable person.
Anyway, my mum and dad have been on holiday for the last week, leaving me and my brother alone in the house. Everything's been fine, and we've both had friends over, but not made too much of a mess or anything. But my parents came back about two hours ago and now my mum's noticed this stain on the bathroom floor which won't come off. It's bright purple and kind of pearly, so pretty obvious really, and being obsessively house-proud, she's furious. As soon as she saw it she yelled at me to come and tell her what it was so she could try to get it off. I explained that I don't know what it is, it's nothing to do with me and I can't help her. I genuinely don't know how it got there. She thinks it's nail varnish, which is apparently her cast-iron proof that I'm responsible, despite the fact that I hardly ever wear nail varnish, I don't have any that colour, and it won't come off with nail varnish remover anyway.
She's said that I can't use the car and I won't get any meals until I tell her what it is, and that if she has to replace the floor in the bathroom, I'll be paying for it. I've now locked myself in my room because I'm so furious with her. I'm not too bothered about the meals, since I can last until tomorrow morning when I go to work and buy something then, but the car is a problem, since I work 30 miles from home and there isn't a direct train route. She's also said that as soon as I go to work tomorrow she's going to go into my room and get all my stuff and chuck it out of the window.
What can I do? She won't believe I don't know anything about it, even though she has no evidence at all that it was me. If it's my brother's fault, he's certainly not going to admit to it now. I can't eat at home, it will take me 2 hours to get to work by public transport (and cost me around £15 per day), and if she follows through on her threat to trash all my stuff, I'm going to have that to deal with as well.
Help!
