One of my friends lent me a book. It has been ruined, by my cat weeing on it . It is a textbook, that will cost £50 to replace . Possibly not my fault, and I feel terrible, but I cant return it in the state it is in.
My plan is to buy a replacement copy of the book and apologise profusely. I feel completely mortified, but plainly I cant let them have the original book back (or own up to what really happened to the book!).
Does that sound OK? Should I do anything extra or anything different?
