The first thing my host father “warmed” me was that almost everyone in America was a big hugger.

I didn’t understand what he meant until my first party. Whether they were friends or strangers, teenagers or elders, girls or guys, everyone I met gave me a big hug.

However, as time went on, I began to understand America’s hugging culture. When a friend broke up with me, I was sad. When I told my best American friend about it, she said nothing but put her arms around me. Then warmth of the hug was a greater comfort than anything she could have said to me.

One winter day I was walking along the street, shivering(颤抖). It was then I saw two women, each holding a paper board, on which there were two words:FREE HUGS. Their were red because of the freezing weather and they were jumping up and down to keep themselves warm. “Hi, girl! Do you want a hug?” One of them asked me. I went up and opened my arms. The hug was short but warm and it took some of the coldness of the day away.

After that I became a big hugger myself. One time my host father and I were traveling to another town. When we reached a restaurant where my friend Cindy worked, he stopped the car.

“What’ wrong?” I asked.” “Alice, why don’t you go inside and give Cindy a hug?” He suggested. I went into the restaurant, ran straight up to Cindy, and gave her a hug before she realized what was going on. “That was a big surprise! And you got my day sweetie! ” She told me later.

A hug is a way to communicate love and care. Do you want a hug? My arms are wide open.
