There was one house on Minuet Drive where the guy who answered the door would make the same joke every month: "Each time I get paid, I throw all my money up to the ceiling. Whatever the Lord wants, he catches and keeps; I spend all the rest." The worst thing was that every time I went there on fast Sunday, they were cooking the most delicious breakfasts. He'd also ask me if I wanted a bite of something before I left.
Funny thing, though. He always put something in the envelope as a fast offering.
