Janeway: When I was a science officer I always envied the captain's priviledge of making first contact with new races.
Chakotay: I envied it so much I almost got shipped back to the academy for remedial training. On my first assignment, we were sent to make first contact with the Tarkanons. I studied all the information we had about them, and pestered the captain into letting me be part of the diplomatic team. When we came face to face with the Tarkanon delegation, I very proudly made the traditional gesture for hello, not realising that males and females of their race use different styles of movement, and I was actually propositioning the ambassador.
