Welcome to the HHCMF club, hophead! The more you do it, the less you think of it as "keeping it up"... it's just something you DO, simple as that.

Edit: Flimflam, I understand where you're coming from. I think I've been more talkative than usual because I'm so excited to be in a place where everyone is speaking English for a change . I usually wouldn't have stopped, but it was in a nice park on a bright and warm summer evening, and I thought I'd give it a go.
