Imagine learning to fly

A family of mute swans - Mum, Dad and the three teenagers - were grazing peacefully, tucking into mid-morning snacks. But you know how teenagers are. Eventually one of them persuaded the other two to take off and cruise over to the other pool to see if there was any more action there. But first they flapped around for a few circuits - just because they could. If you had the novelty of wings as good as this, wouldn't you keep playing with them? Mum and Dad sighed and eventually followed them across just to make sure they didn't get into any more trouble.
