Fairy tale reality?

My 3 year old grandson is very taken with the story of Rapunzel at the moment, so I made him a plait of string to use with the towers he was building with his castle blocks. His little sister enjoyed knocking them down, but even she was a little intrigued by the "hair".
I went to fetch W from his pre-school today, and he rushed to hug his sister before coming over to us! Long may this last!
