This is from an old friend of mine. When her oldest brother was little, he was crying at school all day, and his mom had to come to the school to see what was wrong.
He had seen the "Cream of Wheat" commercial where the cereal stayed with you all day, and a cartoon of the cereal bowl followed you all over.
He was upset because the cereal didn't follow him to school.
