Do any other animals, apart from humans, experience adolescence?
Yes, sheep do, but it's shortlived. For a few weeks the lambs skip and play, keeping well in sight of Mum. Then suddenly they seem altogether more muscular. The look in their eye changes. They escape under gates and over hedges, and hang about in small groups on the corner of lanes. The stance is unmistakable: huddled, heads together, mostly backs to the road and casting surly glances over their shoulders at passers-by. As a former teacher I have a strong urge to tell them off.
Then, one morning, it's all over. They're back in the field, chewing monotonously.
