Lost Marbles

I was in the classroom as some of the children were arriving I went to my drawers to get out something I then walked back to the other side of the room and realised I had forgotten something else so I went back " What are you doing Mrs F? K asked "Oh K I think I've lost my marbles this morning"
"Don't worry I'll look for them for you" she answered. Bless her she didn't quite get my humour but never mind it made my day.
