She watched her supervisor as he entered the conference room. He paused at the side table and nabbed a doughnut before he continued to approach her, and took a bite out of it as he sat, two chairs away.

'You didn't think I was going to drop our little argument, did you?' he addressed her around bits of dough and icing.

She averted her gaze and fixed it on the folder in front of her, then realized too late that he had deliberately spoken with his mouth full in order to prompt her to do exactly that. Was the man incapable of interacting with her without pushing as many of her psychological buttons as possible? He must be a Scorpio. It was the only explanation for the way he treated her: her and everyone else she had watched him deal with.
