After much bickering and complaining between the two kids...
Me: "If you don't have anything positive to say...I don't want you to say anything at all. No more negative talk."
10 seconds later...
Noah: "Maaaahhhm! Natalie is sticking her tongue out at me!"
Me: "I thought I said I only wanted to hear positive things."
Noah: "But I am being positive!"
Me: "How is that positive?"
Noah: "Positive means something that is the truth."
