I had a friend ask to borrow my cordless saw to finish his basement. I was gloating that I had a new one. I don't like loaning my tools anyway, but he's a friend. He was cutting a 2x4 board held up on his leg, well should I explain more. Yes, he ruined his jeans, cut a quarter inch deep two inch long cut in his leg and now is out of work. His wife was mad at me, I should have given him instructions. Instructions, I needed to loan some common sense. No, I should have loaned him my boys Little Tykes plastic saw. Do I need to get a lawyer or be worried?
