A person who seeks for sense of gratitude from others is the person who doesnt know how to apply it to his own being. He who only sees himself as a giver is the one indebted big time to someone else. So let us not live in deceit and become self righteous for a simple act of goodwill because maybe once upon a time in our lives we needed a favour from others, and we have forgotten that we owe them something as well. Just remember life is a two way road.
