Watch out Wonder Woman!

A few days ago I was asking Aiden if he was sick of his cast yet.
Aiden: No, it's cool because it's hard.
Me: That makes it cool, huh?
Aiden: Yeah, if someone throws a rock at me, I can't feel it.
Me: What if it's not at your arm?
Aiden: I just (he moves his casted arm around as if warding off rocks being thrown at him).
Me: Wow, just like Wonder Woman.
