Humpty Dumpty

My Grandson came to play today. Granson A made some salt dough and when cooled wished to make a wall to sit Humpty Dumpy on. Spent the hour building a wall and helping Humpty to fall off the wall and putting him back again. Little Grandson wanted to know how Humpty Dumpty fell off the wall, Just glad the question was not 'why' did he fall off the wall.
