It's one thing to annoy the library patrons (often, it's a good thing), but making yourself a bloody nuisance to your co-workers by constantly talking about your cats, your dumb kids, or your boring weekend is just unacceptable. Seriously, nobody wants to hear it. Save it for when you get on the subway and bother a stranger with that crap. And, above all, do not tell me about that awesome dream you had last night about you hanging out with the Olsen twins and the guy from Bright Eyes. I won't even feign amusement when someone tells me about their dreams. Keep a journal, or something.
