Voted interested, but that doesn't really complete the picture. While I'm not in risk of having her top my scores, she does enjoy playing (just not waiting for me to get done with my ball). Whenever she gets down on her scores compared to mine, I just remind her that the competition isn't between us, but against the machine. I do keep a list of her top scores separate.
However, when it comes to the hobby overall...she once (seriously) suggested that rather than rework the built-in entertainment center to accommodate our too-large TV, that we could just take the whole thing out and fit 3 pins in its place.
So, while she maybe just interested in playing the machines, she is supportive of the hobby in spades.
