T.P. Anyone?

We've been TP-ed a couple times within the last month. When Kenny was serving in the Young Men, it used to happen pretty regularly. The youth said they wouldn't do it if they didn't like us. Usually it was done by Robert who also babysat our kids. At first the boys (especially Mckay) would get mad that somebody made a mess in our yard, but when we explained to them that Robert was playing a silly trick on us, they thought it was fun and would tell Robert to come clean it up. Well, Robert moved to California to live with his Dad last year, so it has been a while. A couple weeks ago though, we noticed TP flying in our trees again and the boys thought Robert was back in town. After talking to several other families that were hit, we discovered the culprit. Kenny mentioned something to him at church on Sunday and his eyes got real big and asked "HOW DO YOU KNOW?"
