<s>[INST] context: Today, I felt terrible. My head was full of problems and confusion . I decided to take a walk even though I didn't know where to go. The most special thing happened when I was out for this walk.
I saw an old man sitting on a chair. He was a seller of second-hand shoes. I thought he looked at least 70 years old. He seemed so tired and nobody was buying his shoes. I wanted to give him something but I had not brought anything with me.
Then, a little girl came toward him. I heard the child say, "Grandfather, may I polish   your shoes?" That old man took pity on her, smiled and gave her a shoe to polish.
The girl told him she needed money to buy her brother a new school uniform.
"Oh, little girl. Just stop doing this. Come with me and I will buy you a uniform." Then they walked to a market , and he bought her brother a uniform.
The girl said "thanks" to him and left, leaving the old man smiling.
He walked away from the market, but I stopped him. I whispered in his ear, "You are a hero! Thank you for your kindness!"  As I walked away, I looked back and I could see him still smiling.
I was blown away by the kindness I had just seen.  Someone who had so little was so generous! Amazing! My own sadness had completely disappeared, chased way by the light of this kind act.
I began realizing that I have a lot to be thankful for. I hope, some day, I can show my appreciation   of what I have by following the example of the old man. He only had a little, but shared it so beautifully with someone who had nothing.
