Asking on behalf of a friend.
She lent a Louis Vuitton weekend bag to a friend as she was going away. The bag cost £4k. The bag is now covered in marker pen thanks to a toddler and it won't come off. Her friend won't offer to buy her a new one and has basically told her to f**k off as it's not her bag, not her problem 
.
My friend acknowledges that she didn't say, if you break/ lose it, you pay for it.
What can she do? Small claims court?
