Will gives his young cousin Jak a few lessons in tree climbing while my sister-in-law looks on anxiously. 'Don't worry!' Will shouts. 'It's fine!' Mem doesn't look too convinced. I don't blame her.
I must have spent several years of my life standing quaking beneath tree branches/climbing frames/neighbours's roofs, ready to catch Will if he fell. Now I keep my distance and tell myself he's old enough to look after himself - and anyway, he'd squash me if he landed on me!
