Meredith Grey: They're everywhere. All the time. Izzie's all perky, and George does this thing where he's helpful and considerate. They share food, and they say things, and they move things and they breathe. Ugh. They're, like, happy.
Cristina Yang: Kick them out.
Meredith Grey: I can't kick them out. They just moved in. I asked them to move in.
Cristina Yang: So what? You're just gonna repress everything in a deep, dark, twisted place until, one day, you snap and kill them?
Meredith Grey: Yep.
Cristina Yang: This is why we are friends.
