Dear Arizona,
   My friend wanted to borrow my favorite book, and I said no because I didn’t want it to get messed up. Now my friend is mad at me. Do you think I was wrong to say no?

Dear Wondering,
   To be completely honest, if I’d read your letter a couple of months ago, I might have thought that you were worrying too much about your stuff. But something happened between then and now that made me rethink the whole lending-and-borrowing deal.
