No, I didn't spell it wrong - this is how Ethan says "opposite." The boys like watching a show called Little Bear, and in one episode Little Bear declared "opposite day." I knew Ethan would catch on, and do that himself. He has several times since then. It is quite cute. The funny part...he'll say "I don't want to talk to Daddy on the phone." Me, "Okay." Ethan, "I really do want to talk t him."
Even though it's opposite day, sometimes he still clarifies what he really means, thinking I have forgotten and then it won't happen. It cracks me up. I love watching and listening to his 5 year old mind!
