As I crossed the playground this morning, I notice two boys leaning on some railings, 'sighting'down the 'barrel' of their hockey sticks as they took aim at a group of chidlren hanging around outside the changing rooms.
I couldn't resist it.
Walking up to them, I whispered: "It's no good. It's not loaded."
One boy looked at me, startled. He nodded, lowered his 'rifle', checked the breech and reloaded.
I laughed all the way to the staff room - and beyond.
