What's That Sound, Mama?

This is what Cael asks a million times a day now that he is Mr. Chatterbox. It drives us crazy. His ears are so sharp he hears every single thing. The fridge hum. The a/c. The next door neighbor's phone.
He also has an attitude now. He frowns and looks from the corners of his eyes to show his displeasure. I have no idea where he learned that.
We bought him a jeep. He is still learning how to steer it. I took some vids but have not been able to upload onto Youtube. It is a neverending frustration. Did not work on Internet Explorer nor Mozilla.
