I can remember being an F/O and thinking certain captains were a pain in the ass etc etc. But now I am a captain things havent changed much really, there are those you enjoy flying with and those you dont, some you just dont remember!!
It all boils down to human nature, the one thing i would remind some F/Os is that nearly all Captains were F/Os once so we DO know what it is like to sit in the right hand seat.
