Like WHO?

Corbin is in this stage of everything being very negative. His favorite answer is "no!" His comments are all presented as dire and upsetting, even the ones he's excited about, like the "po-ise car!" And if he's talking and you're not listening, he's yelling at you to pay attention to him. So in the car today, he's yelling because I'm talking to Eliana and not him, and I sighed and said, "Corbin, you're impossible." Eliana asked what that meant. I replied that it's kinda frustrating how everything he says is complaining or yelling. And Eliana replies, "Oh. Kinda like Sharpay!"
