[Jan's stubborn spine regains its steel, her brows knitting together; if she was allowed to make a noise, she might have spat just to prove a point. she already apologized for staring, didn't she? if this person is waiting for her to change her general way of conducting herself when she's trying to get back on balance and make amends, they'll have to keep waiting till hell freezes over.]

pls. i ain't never been polite a day in my life

[that double negative should definitely read as another "fuck": pure stubborn defiance. Jan knows what some people think of her working-class West Coast vocabulary, and if they have a problem with it, they can go fuck themselves... in her humble opinion.]
