Gamemastering Accomplishments

I cannot help but feel that running a gaming scenario in which one of the players thought the most sensible thing he could do at one point was talk to some moss demonstrates that I have achieved some fundamental victory state.

Me: "Fyodor [party NPC for this adventure] is looking at you like you're someone who just spent five minutes talking to moss."
Other player: "GABRIEL IS JOINING HIM IN THIS ACTIVITY."
