Practically...

I decided.
Decided what?
I am leaving you?
WHAT? What was that?
I AM leaving you.
For who? That, that stupid pin-doll colleague of yours?
Yes, her.
Are you crazy??? What do you see in her, what does she have that I don't?
Its not about what she has, it’s about what she does.
Does? What does she do with you? What does she do that I don't, or that I can’t?
She laughs at my jokes.
