I'm against conceding, but just "giving up" is worse.

I faced off against a coach who after a few lucky turns of me, just stopped moving and pressed the end turn button. This triggered my anger, and I went on a rampant fouling spree. If you don't want to play me, then either concede or just fight back. Don't go and press end turn. It frustrates me greatly, and makes me look suspicious when I didn't agree into him not moving at all.

Guys, if you get hurt and a bad dice game, instead of just giving up, fight back, or hell, if you MUST, concede.
