Joffrey is rude. [It's better than "shithead" or "mean bitch" which are the first two things that came to mind.] And he's wrong. I know a lot more about sharks than he does.

Would it be better if you held onto me like a piggyback ride and I swam? [That's basically what he'd make her do to get over the rocks, only he's way better at swimming than climbing.]
