Ouchies, Owies and Booboos

Today one of my preschoolers came up to me nearly in tears. "I've got an owie on my foot." I helped him take off his shoe and sock and looked at his foot but I couldn't find anything. Neither could he. I found a scrap of something in his shoe, so I guessed that was the problem. He said that was it. Then he looked at his foot again and said, "actually the owie was here but it got sucked in."
