It was a cold afternoon. Ginny and I were walking home after work when suddenly a young man asked us, "Do you want a hug（拥抱）?”He carried a sign in his hand which read "Free Hugo". I looked and noticed there were other young people with him. They all lifted their handmade signs high. The message was the same on all of them - Free Hugs!
"Sure!" Ginny smiled and hugged him with all the she had in her heart,
"WOW!" he shouted. "That is the best hug I've had all day!"
Then the young man looked at me and asked, 'How about a hug?"
"You got it!" I walked into his arms. We held a hug briefly（简短地）and parted at once.
Ginny and I stepped back and watched the "free huggers" hug those who them. All of the young people offered hugs to them.
Not all the people accepted their offers, but the fact was that those who opened their arms in return, walked away with on their faces.
I felt warmth in my heart. So warm that it seemed as if it were not a cold winter day. At that time, Ginny and I were going through times. We had little money and were heavily in debt(负债). We were stressed and , but that afternoon, for a short moment, we ___ all our problems because of a hug with love.
It took a simple hug to make everyone smile and make everything better.
