I forgot

Our oldest was just 5 and at that stage where he couldn't concentrate for long on anything. Dad had asked him to tidy the toys away in his bedroom before we were due to go out. Some time later dad walked in and found him happily playing. Dad was annoyed and asked "What have you been doing - I asked you to put your toys away" a very flustered little boy jumped up and said "I have obviously been doing something - I just can't remember what!"
