DD is 14. She is always wanting to borrow things of mine. Sometimes she asks, but quite often she helps herself without bothering to ask.
I do lend her t-shirts and suchlike but there are things I am not happy for her to borrow, eg expensive coats. Recently she wore a cream jacket of mine to school (without permission) and it came back dirty and with biro on it - the precise reason I didn't want her to borrow it in the first place.
I got an expensive camera for Christmas. Now her camera isn't good enough for all the squillions of photos she takes of herself and her mates and she wants to borrow mine.
And lending her something once clearly sets a precedent in her mind, which makes me even less inclined to lend her things.
Where am I going wrong?
