Two months ago, when I went to the store, I saw a homeless person who was sitting and asking for food.When I was at the store and bought myself food, I bought him bread and water.When I left the store and gave him this food, he was very happy and thanked me, so I did a good deal to a homeless person.What happened to him was not known to me, but I know one good always returns and maybe someday I will not help him, but he will help me.

When I was at the store, I bought food for myself, and I also bought some bread and water for him. When I left the store and gave a homeless person this food, he was very happy and thanked me a lot, so I did a good deed to a homeless person. I do not know what happened to him, but I know that good deeds always come back around and maybe someday he will help me as I helped him.
