Latent hostility.

Earlier this week, the sun was shining temptingly outside and Nat and I decide to talk a brief walk. As we come back in, we bump into her boss, who is walking outside as we go in. We exchange pleasantries about the weather:

Me: "It's lovely out there."
Nat's boss: "Yes, I was outside earlier and it's really nice."
Me:"Sure is tough to come back in."
Nat's boss: "Well, off I go."
Nat: "And don't come back!!"

The weird thing was, Nat just continues the conversation we'd been having as though she hadn't just told her boss to get the hell out.
