There's a small river nearby our house, we often walk along there.
From a bridge you can see grass growing on the riverbed.
It looks like combed by the water.
Do you know "The Grass Harp" by Truman Capote? If not, read it!
It's my absolutely favourite novel, so funny and deeply touching.
I read it about five or six times and it always blew my mind.
Have a look at this beautiful site about Truman Capote.
