You are so lucky if you have confidant. Between two trusted friends their always lies camaraderie. Amity is more than affinity; just because you like someone doesn’t make him your friend. Amity takes more than that. Those who believe in camaraderie always reconcile after quarrel. An intimate or cordial friend may be committed to you as a concomitant. Propinquity built upon how affable and gregarious you are. If you are amiable/amicable/debonair enough, it is conducive for a happy life. It is very normal that to have consanguinity among relatives but when it becomes nepotism, I don’t support that. Sometimes, we friends convene at a place, it increases our affinity.  Maybe some words are not common, they are ancillary. Excuse me for that. Friendship is so important even a congenital child deserve congenial attitude from you. :D
