Either me or him

You rather choose him and don't choose your bestfriend,me!
Why?can I know why?What a stupid choice for you,
I know you since we are still 4 years old,
And at last,you choose a friend that you just know him since this year,
Wow,so great...Non-Sense answer for me...
And now,finally I understand that,friendship is not depends on how long do you know him,or how deeply do you know him.
It's depends on how close that you with him.
