Andrew's just trying to make it through Picture Day, which is easier said than done when it seems like the whole world is out to get him - from a bully to a science experiment gone wrong to a someone else's juice snot (don't ask). But as Andrew goes through the school day, and as one thing after another goes wrong, that little kernel of worry in his stomach is getting hotter and hotter, until it threatens to pop and turn into a public panic attack, his worst fear. He tries to keep his anxiety at bay, but the news that his grandmother with Alzheimer's is missing is too much.
