HMMMMM!

Chase has this thing that he does. When he is thinking he stops and says "hmmmmm" as if he is really comtemplating where the puzzle piece belongs. And, I suppose he is. I think it is just adorable when he does it. But, I wonder where he learned this from? Is it just something that is within him, a little piece of what makes him Chase? Or, is it a learned behavior? This made me wonder if I do it too? Could it be that I just never noticed. In the last few days I seem to do it all the time. Is this a behavior I learned from him, is that even possible? I know I do it intentionally, constantly, just so he will mimic me. But, do I "hmmm" when I am thinking? Just leaves me saying "hmmmmm!"
