Yesterday afternoon，my parents and I go to the supermarket near my home buy some food．On the way back home, I saw several teenager of my age walking aimless around the square．They were shaking with cold and looked even if they were very hungry．It was such a cold night that I felt pity for him．I remembered the food we had bought it and gave it to them．Then we walked home silently．I felt happy to be able to give them hand. My parents also felt very proud at me．They said we should do all we could to helping people who are in difficulty．
