A collaborative story, written by Tomas (age 40) and Mohawk Boy (age 6).

She heard a twig snap.
On the tree.
"Maybe it's my brother," sister thought.
But it was her brother's snapping clams.
They were giant clams and they were coming to get her!
So she yelled "Mom! Brother's snapping clams are chasing me again!"
A clam snapped, and got her by the leg.
And then it dide.
Her leg was broken, but she stumbled on.
With her broken leg.
"Who am I?" she thought.
Am I stupid?
