My daughter came into the house today covered in mud. "What the heck happened to you?" I asked. "I fell into quicksand," she replied. "What?" I said. "We don't have quicksand!" "Yeah we do. It's by the frog pond." "How do you know it's quicksand?" "Because it came up to my knees when I stepped in it." "Okay," I said. "Go clean yourself up, and next time watch out for that quicksand." So now I guess I have to worry about my kids falling into quicksand. Marvelous!
