Our neighbor loaned me his old chain saw to trim some tree branches.

Unfortunately, the engine burned out while I was using it. Not
wanting to return a broken piece of equipment, I bought a new saw to
replace it.

When I offered it to our neighbor, he thanked me but said, "Keep it.
I'll just borrow it when I need it."

I was turning away when his eyes lit up. "Hey," he asked, "want to
borrow my truck?"
