On a visit to my home state, I had a chance to drive through Cazenovia, a village on the shores of Lake Cazenovia. It seemed to me as if in a dream. I saw again the lakeshore meadow(草地)that has always remained an unforgettable part of my childhood memory. It was the place of family picnics(野炊).

It was Grandma who had made it a rule to have the annual(每年的) outing. She had made known her wish that the family should meet each summer when travel was easier and eat together in the open air. It was her pleasure to have all her children, and their children, gather in the meadow, and spend the day eating, singing, playing, chatting, making jokes.

After so many years, I can still see her in my mind, a large figure, dressed in black although it was summer, seated under the shade of a large tree. The others spread around her, sitting on blankets on the grass. Despite(尽管) the joy, the family picnic was also a time of puzzlement(迷惑) for me. Who was this stranger in black with whom I could not speak?

What I knew of my grandmother, I heard from my mother: she believed in good food on the table. She knew you are what you eat and she loved America for all kinds of foods it provided to people like her, who, back in her home country, had been used to a simple life, with so little food.

We were about fifty kin (家族成员)gathered in that meadow, living proof of the family progress. Grandma’s sons and daughters all offered her services, goods and children. And yet, despite the good times and good food and the happy chatting people, I still felt a sense of strangeness. When I asked my mother why Grandma looked so strange and never spoke to us, I was told that Grandma’s home country was in Europe and she didn’t speak our language. In my eyes, she might as well have been from Mars(火星). I never remember hearing our own mother speak to her mother, although she must have. I only remember my shock at mother’s sadness when Grandma died. Was she crying for the silence that had existed like a wall between them?......
