I'm not going to go off on a third grade boy for joining the Muslim prayers of his peers.
My youngest daughter was about that age when I caught her praying at a Shinto shine in Japan. It was a perfectly natural thing to do when we were making a touristy visit and she saw the other Japanese doing it.
At an appropriate private time not long afterward, I explained to her that, as Christians, we prayed in the name of Jesus Christ. I neither scolded nor punished her. She understood and it did not happen again.
Do you think anyone ever told 0baMao that he shouldn’t pray Muslim prayers?
