I had an ultra-hot GF once, who also happened to be really fucking smart -- a jackpot kind of girl. She is the type who gets hit on randomly on the street or subway; or harassed in the clubs (dudes can be animals).
There was always some sort of curiosity in her for hobby gaming, mostly because her father was somewhat of a geek and she was surrounded by the medium growing up.
When we got together, there was a genuine interest in "learning" to play RPGs. I made it sound fun, was passionate about it, and it would've been just another thing we could do together. So I took her with me. We played Savage Worlds and she did really, really well, so much so, that my pal -- who was the host -- enthusiastically called me up the next day to tell me he saldomly has seen a newbie engage so well with the hobby like she did.
Sadly, she didn't like it at all. She tried. It wasn't for her. Even though she played well, purported to the endeavour, and made it seem like she was into it, she just wasn't.
She wasn't faking it. She just wanted to be part of it. Good thing is, she didn't pursue it further when she saw, that it wasn't for her. I wouldn't have wanted her to be there just because I was, just to bore herself to death. To some degree, I was proud of her decision.
