There is no other explanation! Us grown-ups were out in the lounge, hanging out after tea, and the kiddlies were listening to "Now That's What I Call Music 18" rather LOUDLY in one of the other rooms. When I snuck in with my camera to see what they were up to, they weren't the least bit shy to show me their 'moves'. Oh dear. Wait until they discover alcohol. Trouble ahead, me thinks!
