How many best friends do you have?
My son Klay has about fifteen. He uses that term very freely. If you’re playing with him and it’s going well he’s probably going to tell you, “You’re my best friend.”
He’s not being manipulative in his use of the term. He’s just very situational.
I’ve noticed the same thing among adults. We have lots of “best friends”, and I don’t really think the culture of friendship we’re creating is very good for us.
“Best friend” is a very sacred title.
It implies that someone has significant influence in your life and that you, inversely, have great access to theirs. A best friend is someone who knows you inside and out, with all the ugly and broken. A best friend is also someone you can find rest with, simply be who you are, and be fully accepted for that.
We don’t stumble across those friends often.
