I quit loaning things out a long time ago. It always ended up having to be replaced. My DH used to loan the lawn mower to our BIL. I was home one day and going to mow the yard. Mower was gone. BIL loaned it out to a neighbor of his. I called DH who thought it should've been home by the time I got home. When we got it back. The motor was shot because they used the wrong kind of mix of oil. They added gas thinking we wouldn't know. The machine had to be replaced. Over $400 for a new mower at our expense. I got a new lock to put on the shed door. BIL was not happy when we told him he would have to find another way to mow his yard. Good pair of scissors might work. Because of their having no respect for anything borrowed, we shelled out over $1000.00 in replacement or repair. So no more!
