It's pretty easy to tell when you could give 2 sh*ts about the subject at hand

Huh.. Thanks, I had no idea that that was the case.

What's interesting is that I honestly think that I'm not really no-bullshit -- there are a few people in my social circle who (I think) I'm perfectly pleasant to despite my actual feelings about them, in order to not rock the boat of the social circle in question.

Of course, if it's possible for others to guess who they are, maybe I'm just giving too much credit to my dissembling skills.
