did it happen like this I was asked years later

I never quite understood why.
They kept it quiet for such a long time
Then I was asked through a grin
"want to see something nasty?'
Moving through the first autumn leaves
led by the youngster id watched grow

I couldn't see, it was dark
But the sun was blazing
I saw cans and rubbish
It smells, I drew back

'No, you have to see, you came'
I heard a plea from my little wizard
Pushed and stumbling I saw
The hair on crushed cans
Oh the smell, what is this?

I cried that night after the phone rang
Who knew him?
Why was he forgotten?
When did he go for his last sleep?
Why oh why did the children not speak??
