One such day back when Calvin was probably five or six we pulled into the Kmart parking lot right after church. As we started to pull into a parking spot Calvin hollered from the back seat, "No shopping on Sunday!!!"
Olaf kept on rolling, never stopped, and we went right home. Apparently whatever we needed wasn't so important that we had to have it right away.
Thinking we had great boys who listened at church we praised them. Until the following Tuesday when I went back to Kmart with the boys in the back seat. As Calvin and Middle Child both hollered, "No shopping on Tuesday!!" I began to suspect their Sunday Shopping comment had been more of an effort to not shop, their most despised activity, rather than to obey the Ten Commandments.
