Hello, Elle!
Some ladies put their hair up in a bun.
Surely to goodness you know that?
Are you sure you went to school?
Chambers, "bun", "hair formed into a rounded mass."
My grandson has just graduated, so must be 21 or so?
I am hopeless with ages!
I did know they were Seabrooks, the brothers.
Possibly from Lyn M. I am not sure.
Yes, an "ai" is a three toed sloth and it's face seems to have a permanent smile.
They look very friendly sloths.
Robins are members of the chat family, too, and whinchats.
I looked up Michael Morpurgo and have bought another of his books.
"Private Peaceful".
He gets great reviews for his books, on Amazon.
