Is it a fish? Is it a bird?

This a strange doodle but there was a strange visitor in our street on Friday.
There was a man with a zeppelin walking up the street.
The children were on their way to school with mothers and friends
and they all stopped to gaze upwards.
"Is it a fish?" said one.
"Come on" said the mothers. "You're going to be late."

Education is a bit like that.
Don't wonder about fish floating in the sky.
There are important things like getting to school on time.
