The people dressed in green clothes with pointy hats gave me the impression that if I sit on their leader's knee then I'll be made to feel better.
Then there was a toy train set on display.
I went to touch it but the man with a beard dressed in red said
"Don't touch that, my son, have you got a death wish", and he looked at one of his workers and laughed.
I think they might work for the NHS.
