Carlisle, the fact you are even attempting manners makes you the better guy here, full stop. But he still notices that reaction- what is with him and the term? Taako carries it like a badge of honor, a recognition of his accomplishments, everything he fought for to keep himself alive. It's hard to learn magic. Even harder without some kind of schooling. And while the twins eventually made it to an academy, being a wizard was always the goal. He's maybe taking it a bit more personally than he has to.

"Fine, gosh. I can maybe do that. Loooootta magic though." He raises an eyebrow at Carlisle and thinks about taking his leave, but then absolutely doesn't. "Which you know, I learned how to do. At wizard school. Which is for wizards. Because I am one. A wizard."
