I can easily and frequently do fly 6 hours without idle chit chat....Never have understood the need to “vomit” all over a complete stranger. Frequently never have seen or heard of the copilot before and likely will not see them again....and likely dont want to see or hear from them again either.....Layovers are to get a little rest and time away from the stranger that you are trapped like a rat with in a 6’x5’ cell for hours on end
