Storm no longer had to play politely unless she felt the need to. As this wasn't a moment when they were working on something, partners toward a common goal, she didn't see the need to keep up a conversation. In fact, she followed her first instinct, which was get up and go. With a nod of her head, in acknowledgment of Selene, she got up from her seat.
"My apologies, but this was just a moment to get out of my office. I have to get back to work." A touch of a smile, but nothing that could be considered warm in any way. However, she didn't rush away. She took a moment to allow Selene to actually say something in reply. No need in being utterly rude about the whole encounter.
