I really hate borrowing and lending, and try not to do it very often. If I do borrow something I make sure I return it within a few days. If I loan something I expect the same. A former friend used to borrow things and because she was a friend I always hated to tell her no, so just let her borrow but I really didn't like it. Especially one time when she borrowed a wedding sampler cross stitch pattern. I had used the pattern once, for my son, and wanted to use it again for my daughter so I told her I needed it back. Well, I saw it a couple of times while she was using it and she got it so torn and dog-eared that I just went out and bought another. She never did return it.
