My youngest grandson - Austin Giles Snyder - born November 25, 2009.
It looks like he's been searching for the words with which to express his disapproval of something he has just noticed about his immediate environment and is just about to realize that he doesn't know any words yet, which is another thing he's about to disapprove of, except that the same problem with not knowing any words is going to come into play there as well, in consequence of all of which he can't do much of anything except get that expression on his face.
