There's a coworker of mine who bugs the everlovin' shit outta' me. She drives me batty. Her laugh even annoys me. You know how sometimes there are just people who rub you the wrong way? She's that person. I've talked about her before, she's the one who doesn't "do" birthdays.
She won't sign the birthday card or chip in for a gift, but she'll attend the birthday lunch.
She apparently also doesn't do potlucks! Guess what? She won't bring a dish, but she'll sure as hell eat at the potluck!
Maybe she can't afford to bring a dish, you say? I can't afford to bring a dish, but I say so. I am not ashamed to say, "Sorry, not this time, no money." And if I don't contribute then I don't eat it, it's that simple.
