I teach my kids to critique everything they read. For example, in a Dr. Seuss book: “How many fingers do I see…Eleven? This is something new, I wish I had 11 too!”
I asked the kids why we would not wish for 11 fingers, they said we should be happy with the way Hashem made us. I asked them to come up with a substitute for that line.
Our family’s version is “…I’m glad I have ten, like you!”
Another story we read is about some porters who lied to a passenger about what happened to part of her luggage. At the end of the story, my kids sing “Midvar sheker tirchak” (and one kid likes to yell at the picture of the porters, “Liar, liar, pacifier…”)
