I've never been overly popular but have always had friends.
And whilst at different points in my life I've had friends I feel close to, and would class as my closest friend, I've never been anyone's closest/best friend.
Even my dh who adores me, says I'm not his closest friend as I'm his wife, so not his closest friend as they are not the same thing.
AIBU to wish I was someone's dearest friend?
