"Oh, I see. Yeah, that makes sense." Honestly he's also stopped aging but he's still a teenager so he hasn't really noticed. "'Older than I look' is something I've encountered with a good few people so far. Honestly a lot of creatures are older than they look." Even giants and trolls are older than they look.

It's fine, he's not really all that good at social cues so he didn't even really notice. "He's -" The bird breaks into a series of weird noises and Casper rolls his eyes. "Yes, yes, you're very funny, now can you -" Squaaaawk! "Watch your language! Even if I'm the only one who can understand you that doesn't mean you can swear like that. I taught you better than that."

He looks up and scratches the top of his head. "Sorry. He's uh... mouthy. Beaky?"
