I love pushing buttons.
Meeting someone new, talking to them. I love the verbal thrust, parrying, probing for their weak spot and then ever so gently, prodding it.

Ouch.

The knee-jerk reactions, their defensiveness. Not in a cruel way, just learning about them, and how they work. A way of analyzing their sense of humor, inspecting their thought patterns. Teasing, flirting, playing.

Admit it. You do it too.
And you like it.
