I just I don't understand people who don't respect others property. I will on occasion borrow stuff, but I don't like to make a habit of it. In the back of my mind, I fret about something happening to said borrowed property. I have no problems beating myself up for breaking something of my own, but would be sick to my stomach informing the owner I screwed something up.
I let an acquaintance borrow a small utility trailer. He returned it with missing cotter pin safety, and a burnt-out taillight. Even said the light was working before he borrowed it. So, simple stuff, but if you borrow something you return it in the same or better condition as it was upon borrowing. Chaps me when people don't follow this, so I make the caveat clear to people nowadays.
What's jacked up in
@Bravo 4 situation is the friend didn't make the offer to correct his negligence of the property upon discovery. Had to later call and tell B4 to handle it. I know his friend said he would pay the bill, but that is still bad manners. A gunsmith isn't a magician. Some things just can't be brought back to original condition.
