Problems that aren't important...

What is it about having four characters in a scene that makes it so much harder than three? Three is fine. Three is good. Everyone gets to talk and no one is left out. But you add in just one more person and all of it a sudden it's "where's ____? He was here a few paragraphs ago? Did he wander off again? I told you to use the buddy system. ___? You get back here this instant, mister, or I swear to God I will turn this whole story right around and we're all going home! No one will get a plotline!"

Sigh.
