There's a saying that runs along the lines of "Am I up here because you're down there, or are you down there because I'm up here". It is a partnership, and neither would be there without the other. I've cringed on a number of occasions when the hapless controller has been subject to an unedifying rant from a person "up there" who thought the skies belonged to them alone. Controllers, bless them, always kept their cool. Hats off to you all.
