Yeah, of course some sort of takeoff briefing should be done. As for the "sign", your feel for turbulence might differ a little from mine. The way I see taxiing, one guy drives, the other navigates. In this region we work with people from all over the world who do things a little differently than we do or have done, but as long as you get where you're going, smoothly and safely with some semblance of SOP's, go home and forget about it, tomorrow will be better.
