several years ago, I got my daughter an expensive guitar since she was interested in lessons. Well that didn't work out too well, but I decided to keep the guitar in case she wanted to try again when she was older (or my other daughter might want it). A couple weeks ago, my best friend mentioned she always wanted to take guitar lessons and I replied dd had a guitar she wasn't using. I let her borrow the guitar with the understanding that it would go back to my daughter if she wanted to start lessons this school year (this year she gets free lessons and had mentioned maybe she would try again before my friend took it). I also asked her to please make sure it was put away when she wasn't using it so her kids didn't think it was a toy. You see where this is going? Her youngest son broke it. She felt bad and said she'd replace it, but I feel guilty also since it is older and was not being used at the time. Now dd is interested in lessons, but a different instrument. So here's my questions:
1. should I let her replace the guitar for what it would cost me to replace it? My other daughter has shown interest in it.
2. should I split it with her since it was older, although it was mint condition?
3. should I ask her to use the money it would cost to replace it to buy dd the other instrument (which is cheaper)?
4. should I chalk the whole thing up to 'don't lend friends expensive things' and let it slide?
5. does anyone have another suggestion on how they would handle it?
like I said I feel bad because it wasn't being used in our house, but I'm also upset that she let the kids use it after I asked her not to.
