Friendship is an interesting chapter in our relationships development. Acquaintances, clients, coworkers, even lifelong partners or spouses, CAN have as a basis various degrees and depths of friendship. We can have pseudo friends, quasi friends, loosely attached friends, long distance or even virtual friends. Friends that stand the test of time of loyalty, commitment, trustworthiness earn that "true friend" status. Then we have the BFFs, and I do believe we can have "multiple" Best Friends even if the word kind of implies BEST meaning the top of the mountain, only one. They say in marriage ideally you will marry your BEST friend and it certainly is a rock solid foundation for trying to have that institution LAST.
BUT "who" should NOT be your Best Friend???
I won't even get into the romance topic of SOULMATE and if there is only ONE of them on the planet of seven billion people or not. Hard to believe there is only ONE of them with that many people, and if they are in China and you never visit China how would you meet them? But back to the question of WHO should not be your best friend?
The answer is YOURSELF.
Now you may think you need to like yourself, be good with yourself in your alone times, ONLY YOU know your entire life journey, and what REALLY goes on inside your head, your public and private life.
BUT the reason you need an OUTSIDE you best friend or best friends is you are not the perfect mirror to tell you how to be better. PEOPLE SEE YOU, you looking in the mirror and thinking about yourself is an errored judgment. If you spent 90% of your time enjoying your own company, people will call you a cat lady. Life is meant to be mixed up with others, forcing yourself MUCH of your life to mingle, whether you like to mingle or not. GET OUT there every day, hate it or not, FIND that best friend or friends and talk to them regularly. You will know them when you find them. AND IT IS NOT YOU.
