Best friend is someone u share anything
with.. irrespective of it being relevant or irrelevant to this buddy.. You keep
sharing everything with this mate, at every walk of your life… Your thoughts,
impression on every random person, likes and dislikes, every little thing. “A true friend is someone who you can be transparent with, who is transparent with you, who does not expect you to change and whom you never expect to change”
This might sound a lot similar to a lover.. But there is a lot of difference..
With your lover, everything changes with time.. We meet them as acquaintances,
makes friends with them, get attracted to something about them, talk to them
and stay with them as much as we can, try to impress one another, get into a
relationship with them, get committed, get married, become parents,
grandparents…… At any stage the bond can break.. The involvement and commitment
changes at every stage.. But with a best friend, there are just three stages..
acquaintance, friend and best friend.. 
Not all acquintances become our
friends..not all friends become best friends… At any stage, this thing can get
cut.. but once we are true best friends with somebody, we will remain best
friends for the rest of our lives.. There will be a lot of ego problems with
our partner, but with our best friend, who knows us totally..we will not have
any…
Best friends also have issues, they too fight, they too stay away from each
other without staying in touch for a long time.. But if they are real best
friends, they will know each other well enough to understand and sort the
problem.. It might take time..but in the end, best friends will be best
friends… 
A best friend cannot be lost.. it is totally in our hands to bring
them back as out best friends.. We have every right to slap them and ask them
why they are doing this.. It just needs true love for your friend to do it.. To
make the rest of the journey beautiful, we need them.. Some people are too lucky to have so many such beautiful friends.. but to maintain them for the rest of our lives is not so easy..Like in any other relationship, friends fight. But the issue should be solved as soon as possible. The later it is, the more difficult it is to get back the friend..
Everybody will have a best friend at some point of time.. The challenge is to keep them in their Awesome position as long as we live!!!
Some people get married to their best friends.. In a way it is good. getting married to friends and best friends is totally different. With friends, we are what we are!!! But we don't open up like how we do with our best friends. But with best friends, we are ourselves.. The child in every person comes out in front of the true love and the best friend!! Best friends know us the best!! Even better than the spouse....
Getting into a relationship with a best friend, is not always right. If everything between the two is mutual then there is absolutely no issue. but when it is friendship for one person and love for another and this friendship upgrades to a relationship, then a lot of differences and understandings arise when it comes to the expectations point of view. One person has feelings for the other person but behaves like a best friend. The other person who treats the former as a friend slowly realizes the love for the later. And when they then get into a relationship, things will not be the same.. The friend from the beginning person, expects something more from the lover acting as a friend. but that is all that lover can give because for that person it has been love from the beginning.. 
This totally disappoints the friend.. The lover acting as a friend will be very happy because that person is getting what he always wanted.. but this friend, will be so disappointed that they'll think that "If my best friend couldn't be the one I wanted, can anybody else be that!!!" This phase the person goes through is horrible!! Even the Lover will be hurt because he is not able to reach the expectations of his Love.. If this thing doesnt work, people break up!! But only true friends, continue to be what they were before the relationship, realizing that they were better off or best as BEST FRIENDS..
