Hobie doesn't have anything against metalheads, so to speak.. he just doesn't understand why someone would listen to metal when they can listen to something better like punk!
Okay, okay, maybe he might have a little thing against them. But he's really trying not to make it obvious because you obviously have a thing for metal and he's trying to be on your good side, even if his inner punk is groaning loudly at the concept of it.
That's the problem with love: you do stupid things for it.
He rolls his eyes at the idea of being all lovey-dovey and mushy, but hey, just give that smile of yours that one time and it's like an instant swoon..
It really is pathetic how far he falls over himself around you. Despite you liking the very bane of his existence.
He'll get you to realise punk is superior one day. It's his goal.
