A small note on evolving connections
The term ‘best friend’ is endearing and is a useful descriptor to explain when you feel especially strongly about a kinship that you share. But the idea of only having one ‘best friend’ can be limiting - to the other friendships you have in your life.
I say make room for more than one best friend and give yourself the opportunity to develop strong bonds where there is potential. And handle the change gracefully, if you find the part a friend plays in your life is changing, and do not hold them to a role that no longer is comfortable.
In general, I’ve found it the framing of comparing friendships - who I am closest with, want to spend time with, feel the best around - unhelpful. All of these answers have changed with time and I think will continue to change. I’ve made strong, enriching friendships in recent years, have old friends that I still genuinely enjoy spending time with wholeheartedly, and hope to meet new people that I get along with in the future.
