Maybe it's a "now I'm four thing", I don't know. But I can't get over the fact that Julien thinks he knows everything. And on top of that he corrects me with misinformation!
Example: Yesterday in the car, some music came on between segments on NPR. I am 100% sure that it was fiddling. I'd bet money on it. And Julien says to me "Is that Chinese music?" "No, it's fiddling. You know like a violin, they just play it differenty." His response, "No Mom, it's that Chinese instrument...ching, bang, weng, dong. It sounds much more like Chinese music when Julien does it. Insert audio and visualize him moving his head back and forth! ;0) After that I just let him have that one. Hey, you can argue until you're blue in the face. If he's so sure of himself, I'll let him think he's right.
