Because if you are a Captain, I would think you would display the qualities & traits of of a Captain. Leadership, mentorship , the desire to help your FOs succeed .

Its sounds like your last command was as a Captain of a MS flight sim airliner in your parents basement . If you are a Captain i hope your not some Regional lifer who thinks of him/her self a a big fish in a little pond.

Otherwise, be a Captain, step up and help this guy out!
