I kept thinking of a girl in the school in which I taught before my current one, who was around eleven, twelve, thirteen when I was there. I didn't actually teach her, but I know that in the time I was there I didn't once see her smile. Never. It was easy to guess there was no reason to.
This kind of thing can make you debilitatingly sad, so it's important not to let that happen. And who knows, she might have risen above it all and been better for it. The resilience you see in the most unlikely places is cause for hope.
The world's too big to throw your arms around it. But that's no excuse for making excuses.
