Who comes to Auggie’s birthday party from school?

From the text:

Jack, Summer, Reid, Tristan, and both Maxes came from school, and Christopher came, too—all the way from Bridgeport with his parents. And Uncle Ben came. And Aunt Kate and Uncle Po drove in from Boston, though Tata and Poppa were in Florida for the winter. It was fun because all the grownups ended up bowling in the lane next to ours, so it really felt like there were a lot of people there to celebrate my birthday.
