We were having an 18th birthday for a friend of Son #2's who joined our troop for about a year.
His mom was reminiscing how shortly after he quit attending meetings, the boy had roped them into family camping at Racoon Creek State park. Aptly named, the raccoons consider your food theirs. In the night, the vermin got a hold of some snack left by the campfire. Then they started clawing at the Boy Scout Handbook the boy had left out!
I asked the boy, "If I had known, I would have told you that if you came back to scouts, you would have the coolest handbook by virtue of the claw marks all over it. Would you have re-joined our troop?"
He said, "You know, I might just have considered it."
Got any other one-liners that may or may not convince a youth to change his mind, but would be fun to put out there anyway?
