Prayer etiquette

This morning, I had served up a gourmet school morning breakfast of cereal and milk. After everyone was served, I asked Tyler to offer the prayer. He offered a very nice prayer but as soon as he closed it, the prayer police officer, Olivia, said, "You didn't bless the food". He looked at her and said, "There was nothing hot so I didn't have to". I started to chuckle and Carter (who is so much wiser than his siblings) said, "You bless the food at every meal so that 'it will give us the strength and nourishment we need'".
