'He has a gun.'

'Who? Tell me, where are you? Who has a gun?'

'I love you, Mum.'

An ordinary school day in March, snowflakes falling, classroom freezing, kids squealing with delight, locker-doors slamming. Then the shooting started. No-one dared take one breath...

He's holding a gun to your child's head. One wrong answer and he says he'll shoot.

This morning you waved goodbye to your child. What would you have said if you'd known it might be the last time?
