Friendship is something that creates equality and mutuality, not a reward for finding equality or a way of intensifying existing mutuality.
I love 'Curb Your Enthusiasm' and 'Extras' and also 'The Trip.' That had all the nuances of friendship and finding things out about their lives without it being too much plot-driven.
Finding good players is easy. Getting them to play as a team is another story.
A good friend is a connection to life - a tie to the past, a road to the future, the key to sanity in a totally insane world.
