Lily started 1st grade in the same elementary school that I went to. In fact, when I was a senior in high school I actually taught french with her 1st grade teacher.
These are two of eight poses that Lily wanted to do for the picture. I thought I'd spare you the other six.
I have no idea if he was channeling Elvis or just attempting another "cool guy" pose. It was his senior year of pre-school so that might have influenced him, also.
You can catch a glimpse of his red cast on his left arm. That was a result of jumping out of a baby swing that he shouldn't have been on in the first place. If anyone is counting, this is broken arm #2.
