It’s the beginning of August in California, and that means one thing: after an all-too-brief summer, it’s back-to-school season, and as usual, we have a collection of pictures.

School started on August 8 in San José this year, which feels even earlier than in years past. This particular first day was poignant because it wasn’t just the start of William’s seventh and final year at Booksin, but also the beginning of our final year as Booksin parents. Our time there started with Julia in kindergarten all the way back in 2009; all told, we’ve had fourteen distinct school years at the school, with a year off between the time Joe moved on to middle school and William started TK.

Of course, none of that mattered a bit to Will, who was much more concerned about what fifth grade was going to bring than what things were like during Obama’s first term. His teacher this year is Mr. Lau, and he’s lucky to have some good friends in class with him. Hanging around in the school courtyard before the first bell, he derived obvious energy from being around his pals after two full months away.

We took the usual assortment of pictures in front of the car before we left the house, and you can see the first signs of adolescence starting to creep in at the edges of the posed shots. He remains a joyful, amazing kid, of course, but it’ll be just a couple short years before he’s officially a teen.
