The difference between a Captain and a co-pilot is this:-
when you are a co-pilot you go to work wondering which ****you are going to fly with, whereas as a Captain you already know! But not all the **** sit in the left-hand seat
I was once told that the diff between the skipper and FO is as follows: "When You change from the right to the LEFT seat it is time to stop listening to all the bullsh!t and... start telling it". give it a try!
