Greg's face flushed with his immediate anger at Alfie's verbal jab, and he slid off the table and was closer to the other boy in fast long strides. His hands found both of Alfie's arms, and he moved in closer still, using proximity to intimidate and scare the other boy. Greg knew his face looked furious; it was a bit of an act, as he was not nearly as mad as he looked. But he hoped Alfie would cower at the expression. And he leaned in even more.
"Bullshit. It doesn't just happen like that, even with a girl. One person initiates it. The other sort of invites it. Someone's the bottom. Someone's the top. Which are you? Did you come on to him, strong? Throw yourself at him? Or what?"
Greg paused, and added more.
"You are a fucking liar, you know that? You didn't mean for it to happen? What the fuck?! I thought you'd at least have the balls to be honest about this, especially with someone who knows."
