"First lesson? The sharp things in this apartment are going to bite you," she said mildly, watching him. Not stopping him, just watching. "That may or may not include me."
Half teasing, half serious. Because, well, this was her. She said outrageous things as a way of life. If it got to people, more the better. If it pissed them off? Even better than that.
"Second lesson, I really do behave sometimes," she said. "So no stabbing until you tell me." Which, notice that it doesn't preclude her doing it at some point. Mostly because she likes you, Murphy. She won't put herself out there like that for just anyone.
"Third lesson, you don't gotta worry while you're in here. Safe space. Leave them outside. I mean, you can bitch, but don't worry too much. It wastes energy that, quite frankly, they really don't deserve."
