I would bring it, but I have no idea how since I always fuck it up no matter how tactful I try to be in these situations. calling your game stupid is really nasty and hurtful. My wife used to criticize me only in front of friends but not when we were alone. I eventually convinced her that this was an ugly thing to do to her spouse.
At least my wife likes pinball and had no qualms when I told her I wanted to buy a Houdini (her jaw dropped when she heard the price). She was also totally agreeable to travel to TPF with me. Although she does beat my friends and I on a regular basis.
Ah maybe that will help. let her beat you....
