At tea tonight:
"You better watch it," said Granny, "I've just found a bone in my fish". I think, in her roundabout way, she was reminding Mummy to check my dinner. Mummy is used to this.
"You're lucky then," said Mummy. "I haven't had any"
"I've got a bone in my arm" I piped up, sure that everyone would be interested. And indeed, Daddy was.
"Where have you got another bone?" he inquired.
"In my other arm!"
