[Rude, Professor. Honestly, Tony isn't all that bad. Sure, he's an asshole, but his entire existence isn't built around insults and aggravation, as much as he'd like other's to think it is.

Which is why he's just pulling over a chair, for now, plopping down into it in order to get at Charles' eye level, just kind of giving him a Look.]

You're sulking in a bar, Charles. Drinking alone is pretty much synonymous with hanging a sign above your head saying "I hate the world, buy me a drink or get out."
