I don't mean to criticise you personally Ttex600 because I don't know what else was said. But hypothetically, if manual flying is uncommon at an airline, and a capt decides to do some raw data flying without any verbal preamble at all, I'd be a little scared too. Not of the aircraft, but of what other random ideas the guy to my left is going to throw into the cockpit without warning.
Not every reticent FO is a child of the magenta line. The conversations that captains foster, are the most useful learning tool for me.
