[SNOWBALL]

I hate to say it, but if she doesn't understand eventually then you are either really bad at explaining stuff, or she is just dumber than a sack of bricks. Every single intelligent person I have talked to about poker was able to understand it fairly quickly. The exception is if she really does have very deep rooted issues against gambling.

FWIW, it doesn't sound like she does. If she says "it's useless for society", it sounds like she is just expressing an opinion, and not like she is taking a life or death stand against gambling.

Also, if your poker BR is separate from your regular assets then it's none of her business if you set it in fire. She shouldn't care. Most winning players can lose their entire net worth and still be way way up in regards to poker. In other words, even if you were to go broke tomorrow, you wouldn't have a reason to regret playing poker in the past.
