A great contest to participate. The word called reciprocity is a similar word that is within us, reciprocity means relationship share between two party or group individual that associates in love, kindness, giving and be thoughtful to one another.
Like I said earlier the word reciprocity is common, given out to people who are in need not just people who are in need but people you could share your ideas and love to, being kind to someone when you find someone in a way of needing help and you are capable of rendering help to the person at that moment, and in one way or the other you are also in a mess and some one who you have render help in one way or the other show up and help you, that statement could be called reciprocity.
The love we share to people and to people around us are informed of being kind. I could remember when seeing my grandfather rendering helps to people, given out to the poor and also accommodating people who don't have shelter or where they could laid their head was the relationship he was building for the future.
When he died the memories he kept while he was alive was spreading to his son's and generation to come. We where in need that lead to financial challenges that involved the landlord throwing out are property outside, there was no place to go, but the calls my Dad made brought testimony and happiness one of my Grandpa friend who was wealthy ask us to come over to his place that his house is big enough to accommodate each and every one of us, that my Grandpa was a close friend to him, when he was in trouble he helped him and his family, that he couldn't imagine while his still alive he will let us suffer.
That short true life story was the love my grandpa show to his friend when he was still alive, now his friend has to show same love my grandpa show to him, that relationship keep on growing while my grandpa was died, the love and relationships you create among people will be there no matter your death it will extend to your family and friends.
Reciprocity as the exchange of gratitude and love, exchanging gratitude is common to us and in our society love and kindness as to be ability we do in a daily basis, sharing and exchanging kindness is the main purpose of reciprocity.
