Do your characters wait for you when you take a break from writing?
Mine do. They stay exactly where I leave them and start drumming their fingers on any available surface. They watch me. The less subtle ones may start pacing. No matter how different they are and how at odds their desires and ambitions are, they are unified in their impatience for me to come back and move the story forward.
So if you excuse me, my protagonist and her antagonist will start plotting against me if I don't pay them attention soon.
