When our children misbehaved, I never raised my voice or screamed or made a scene. Don't raise your voice to me or screamed. Scream has got two meanings - shout is just say things very loudly and scream can also mean help. To cave or to cave in means to crumble. Like there's a picture of a cave here, but imagine that the roof of the cave, cave giving way and it collapsing. And eventually they'd cave.
