He's done the old song and dance before. A new school means scrambling to transfer his immunization records, comforting his pets about the new environment, introducing himself to the class when they've known each other for months, if not decades (he likes heavy metal and comics and it's not like being honest about his interests is going to make him more popular but why lie to people he won't ever see again).
So he's bored. It's boring, being the new kid forever. He's not sure what his parents think he's getting out of school. He thinks he'll give it a week before he starts skipping.
