Yesterday afternoon, my parents and I go to the     
supermarket near my home to buy some food. In the              
way back home; I saw several teenager of my age                    
wandering 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           
a  food we had bought and gave it to them. Then we walked
