Tonight Evan grudgingly brushed his teeth, then reached for the glass of water I'd set out for him on the sink and knocked it to the floor. This made him laugh.
Eric (annoyed): "Can you say, 'I'm sorry'?"
Evan: "Why? It's your fault."
Eric: "What? You knocked the water over and I'm about to clean it up! How is that my fault?"
Evan: "You put it in a precarious place."
