Surely Nam won't be pleased if Gaja just grabs at him is right! He spends the majority of his time on his own and even when others come to see him (aside from Gaja, who is the exception), they always keep a certain distance from the dragon. They approach with caution and then give him space. So while he doesn't necessarily react poorly to someone suddenly grabbing at him, he can. But mostly, it just makes him uncomfortable.
