It's all truth, of course, but that doesn't make it any better. This is how Myer thinks, in black and white and shades of who is more right. His rationale is never rooted in cruelty--Adam likes to think he's not the type--but he doesn't mince words with the others and sometimes, feelings do get hurt.
Adam bites his lip, chews the inside of his cheek in an effort to keep silent. Rocking the boat helps no one, but the weaker members of the pack need the most protecting, even if Myer doesn't see it like that. For him, the matter is simple: he'll excuse any behavior by claiming he could do a lot worse. Compassion is not a trait with which he's familiar.
"I know... It's just... Not everyone looks to you to make sense of their lives," Adam points out after a pause during which all humor has drained from his voice. He keeps his eyes on the road now, because it's easier and he's never really liked conflict. Not with the others. Efforts to remember what they were talking about a minute ago come up empty. All he can see is people talking shit behind Austin's back--and chief among them, Myer.
It's unfair, but it's like one of Trixie's word stunts. Once it's taken seed, the idea is impossible to shake off.
