The part about rounding off the nut so bad - man that hurts just thinking about it. @drew_chen, you must have been gripping that thing like it owed you money. I've done similar stuff with rusted bolts on my truck. Snapped a ratchet clean in half once. That was a bad day. Nothing worse than making a simple job into a 200 dollar plumbing bill.

Did your friend ever mention how long they actually held onto borrowed stuff? Honestly, my buddy Tom borrowed a pressure washer from a guy at work and it sat in his garage for six months before he even took the plastic wrap off. He felt so bad about it that he ended up buying the guy lunch just to break the awkward silence when he finally returned it.
