there are many threads on this topic of getting caught, which can go in to more detail, but basically, there are a few conclusions which most people seem to agree with.
- it is probobly not a good idea to just flat out deny it and play dumb. it kils the vibe, and she thinks you're a twat
- you can say "oh, i've heard of that book, it looks good. did you read it? because actually last week on of my girl friends showed this to me, i thought it was awesome"
- you can totally admit to reading it, and ask her if she's read it. if yes, then discuss it because she's obviously interested in the topic if she's read the entire book. if no, then tell her about how it allows men to develop more confidence, social dynamics, etc, which makes them able to go out and take life by the horns...etc...etc...etc....go in to routine
****just plain denying it can be very bad, it might be seen as the equivalent of putting your hand out to take a girl's hand, and she says 'what are you doing?' and you say "oh, ah, nothing!" = asshole.
as opposed to saying "i'm holding your hand" confidently and congruently = wow****
