ПРОВЕРЬТЕ ПОЖАЛУЙСТА ГРАМАТИКУ И Корректность

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.
