Adam & OTA
Adam wouldn't have skipped this even if he wanted to; Katie probably would've thrown a fit if he'd tried. She and Steph were so close in age, and Judith wasn't far off, he was preemptively feeling sorry for everyone once those three hit school together.
Which was going to be soon enough, holy crap.
He'd let Katie go tearing off in search of her friends, not bothering to watch out for her considering who all was there, which meant he was free to mingle. He'd snagged a beer and was now deciding where to start with the food.
