His old pair of shoes was too small for him so we gave him a new pair, one with shoelaces. That day after school when I picked him, he looked very grouchy. He hated the shoelaces cos they kept coming off despite him tying them back again and again. He did not want to wear them anymore.
Daddy came home in the evening and tied a dead knot for the shoes so now Clarence just need to slip his feet in.
So the problem was: mummy did a lousy job in the morning tying his shoelaces for him. Oops!
