Traits Passed On

Can you point out, by chance, what Calvin is doing that is a notable habit of his dad's?

(not the best picture of Cal.. sorry..)

Can't guess?? Let me tell you.

We lovingly call this Perching. Most of the time it's just one knee, sometimes both. But on this occasion, Cal was going about his business, eating his breakfast and then David comes and sits down to eat, too. I had to grab my camera right away to capture this rare father-son likeness! We didn't prompt Cal to do it or anything! His little knee just went up onto his chair. Just like his dad. 

Why me?!
