Friend favoritism

What do y’all think abt friend favoritism?? Cause for me, I think it’s lowkey reasonable. I have some friends and there’s some I’ve known longer than the other, ones that I can talk abt more stuff with, and ones I have looser boundaries towards. And for that, I favorite them over my other friends. I mean, would it not just be reasonable to?
What is your opinion?
Goodnight btw! I’m going to sleep after posting this (ᴗ˳ᴗ)
