Jack: Wendy, let me explain something to you. Whenever you come in here and interrupt me, you're breaking my concentration. You're distracting me, and it'll take time to get back to where I was! Understand? Wendy: Yeah.
Jack: Fine. Now we're going to make a new rule. Whenever I'm in here, and you hear me typing, or whether you don't hear me typing, whatever the fuck you hear me doing in here, when I'm in here, that means I'm working. That means don't come in. Now do you think you can handle that?
Jack: Fine. Why don't you start right now and get the fuck out of here? Hm?
Wendy tries to make conversation with Jack about the forecast and he appears to be grouchy. He starts ranting and raving about how Wendy is a distraction and interrupts too much. In the end he tells her to get the fuck out.
