"As always," Cedric's used to Howard's assessments by now. He doesn't really mean it. Right?

He clambers up and stands next to Howard, looking over the view for a moment. It must've been different in Howard's hometown. "I can't entirely blame you. Maths in Muggle school were hard work, from what I can recall. We have Arithmancy, but it's different."

Very different. Numbers and predictions, all that wizarding weirdness.

Cedric interrupts Howard's apology with his own. "No, it was my fault. I'd be glad to visit. If the offer was still out there."

And he won't blame Howard if it's not.
