Do friends have bonds?

From the childhood we come across many friends some will be dear ones some will be casual friends and the other close friends, why do people differentiate the friends into different categories………The thing behind all these is that there is a bond between every friend with you. Few of the examples are ..If his characteristic are involved till 10% of thoughts they are just friends and if thoughts match 30% they are good friends if there thoughts are 50 %  matched they are best friends if they are same as you in thinking close friends.100% trust an opposite sex person then they call it love. Every friend has some or the other category related to your habits/wishes/colors/likes/actions/thoughts/characteristics or any other sort. If they do not match they never become your friends. Even an enemy is a friend that you hate………Every person need friends to share there thoughts and wishes for encouragement or console…But a friend is a friend and nothing replaces the position…..
