Just carry a small pry bar in my kit.

I read a book on neighborhood ties that said shared physical work builds trust 40% faster than social visits. Your story about the shed nails that idea perfectly. Teaching a skill is about showing patience and believing the other person can do it. That creates a DEEP sense of mutual respect. I heard a similar thing from a local community leader last year, who said projects like this are the glue for strong streets. It's why those shared efforts mean more than just borrowing a cup of sugar.

That "muck like glue" description hits way too close to home.
