DD's friend comes over once a week. She's always touching things she shouldn't be, I assume just out of curiosity but I still think it's rather rude. She says things like "I want some crisps" then goes to get a packet - obviously I stop her and get her to ask politely. She came round yesterday and somehow managed to bend one of our keys (I assume she was trying to force it into the wrong keyhole), tipped over a huge bucket of water in the garden (she'd disappeared while my DDs were playing, I found her in our garden where they'd been previously watering plants) and this morning I found OH's razor in the bathroom with strands of long hair in it! Maybe we should have put it out of her reach but I know my DD would never dream of doing that in someone else's house. She also knows never to touch a razor. I always check on DD & her friends when they're at our house but I feel this girl just wants to rebel and do things she knows she's not allowed to. The way I feel now I don't want her round for a while & I'm thinking of saying something to her mum but we are good friends.
