The Book Clubber
You can learn a lot about a person by what they read. Which begs the question, why are you lurking by the bookshelf trying to learn a lot about a person in the middle of a party where other people are jumping up and down singing:
"No I'm not tryin' to be rude,
But hey pretty girl I'm feelin' you
The way you do the things you do
Remind me of my Lexus coup!"
Are you conducting some kind of psychological profile? Are you going to corner your host later and be all like, "I feel like I know you so well" even though you kinda haven't said more than three words to said host in your entire life? This is going to end weirdly.
