Davenport, CA
I remember very, very distinctly the first time our son touched grass, because it did not go well. He was already six months old - because he was born in October, and we live in New York City, and grass-touching isn't an especially popular pastime during the winter months - so once spring hit we immediately packed up a picnic blanket and popped a tiny fedora on his head and set out with our friends to spend the afternoon watching our son revel in all that glorious grass.
Turned out he hated grass. And sand. And water. And any other naturally-occurring underfoot texture (although he would happily toddle barefoot down the sidewalk, crushing shards of glass and discarded cigarettes under his tiny toes). As a native New Yorker myself, I get this. Grass is creepy, yo. There are so many things that could be in it: needles, broken beer bottles, bugs. Yesterday I saw a two-inch-long slug sitting on my front step, and then a few minutes later it wasn't there.
