(Xo and Xo are working in the lab. At least one of them is.)
Xo: (whispering into Xo's ear) What color is your bra today?
Xo: We're working.
Xo: Answer me!
Xo: Yes. No. Not Often. Yesterday. Mars. -- Want more?
Xo: (unfazed) What color bra are u wearing today?
Xo: I'm not telling you.
Xo: Is it black?
Xo: Is it red? :D
Xo: Certainly, not.
(a couple minutes pass in silence as he stands behind her and plays with her hair)
Xo: What happened? Did u again forget what the other colors are called?
Xo: It's not black or red. So I'm not interested anymore.
(And Xo walks away fiddling with his pen)
