More of a WWYD.
I left a pair of designer sunnies at my friend's house the other day.
Friend has just phoned to say terribly sorry but she borrowed them and has lost them. 
She was hugely apologetic but hasn't made an offer to replace them.
I don't know if she realised that they are quite expensive and that's why she hasn't offered.
AIBU to think that she could have at least asked how much they were/offered to contribute towards replacing them?
