Confess, I assure you, you are not the only one who gets bored of trivial conversations after the first 5 minutes. I always end up with, "I just met you, and ..... is how you've already had such an impact on my life." Then I try to escape conversation.
Or, "Yeah, so, I was, ummmm, playing video games for 10 days straight.... Now I'm thinking about watching grass grow for the next day or two." (Don't get me wrong, video games = fun, but video games non-stop *yawn*)
Or any number of other mundane things.
I'm one of those completely honest people and I have interesting beliefs (according to me), so evasiveness or bigotry and I start wandering off.
