"You're supposed to"

Last week we took the kids to window toy shop at Target. While I was chatting with a lady from our church, LG stopped at the books with the girls. Bella kept requesting LG to read from different books. At one point LeGrand told Bella to hold on. He was attending to Abigail or Sophia. Bella chimed out in a way that was bound to be noticed, "Dad, it says on the TV you are supposed to read to your children." Classic.
