Captain "Sir"
Naw, "Captain God" who sittith on the left side of the aircraft will do fine. (Joke)
Please, it needs to get back to reality and in a very harmonious way. Be kind. Don't demand. Learn as much as you can for when the real time for command comes along.
I know there are some captains who use the uniform and the aircraft as their status in life and that can be intimidating and some times humiliating.
Hopefully they are a disappearing breed but remember they can serve as a good example as to what NOT to be.
Meanwhile, respect the captain who is competent and a high calibre human being and let the jerks go by the wayside.
Happy thoughts to you, my valued First Officer.
