It had started out so harmless. Grif had just been bitching about work, he hadn't known Simmons could hear him.
"What did you just say?" Simmons asked, not quite hurt yet. He was trying to brush it off as a joke. Grif wasn't sure why he'd kept going with it- maybe he was actually mad about all this, maybe he just hadn't been thinking about what he was saying and who he was saying it to- but for some reason he repeated himself.
"I said, of all the fucking people to get body parts from, why'd it have to be Simmons?"
Simmons went quiet before going slightly red. "You're joking, right? I saved your life. You could be a little more grateful!"
"Grateful? Why the hell would I be grateful about getting body parts from one of the weakest guys in the fucking canyon? I could have gotten parts from Sarge or one of the blues, or fuck, even Donut! At least he can throw! But no, I got stuck with an arm and a leg from the weakest guy around here. What can you even do, shoot a rocket launcher? I'm surprised the kickback on that thing doesn't lift your ass clean off the ground!"
"Please, I'm stronger than you'll ever be!"
"You sure as fuck weren't strong enough to pull me up over that cliff, and that was with the robot arm. You can say you're strong all you want, but where the fuck is that strength when it matters?" Grif snapped, glaring.
Simmons, however, was struck silent for a moment. He blinked and swallowed once- the only sign of hurt he let show- before his eyes hardened. "Leave me the hell alone."
"Oh, what's wrong, did I make you mad? Poor fucking you." Grif was angry, but something in the back of his mind was screaming for him to Stop you fucktard, you're making things worse! He was still mad- whether at Simmons or himself he wasn't sure- but he had to try to make things a little better, at least. "I'm real sorry, kissass." There. Even though he'd said the first part sarcastically, he'd called Simmons a kissass. Simmons would reply with his normal fatass, they'd go their separate ways to calm down, and then they'd make up and everything would be oka-
"I said, leave me the hell alone. Just get the fuck away from me, would you?" he asked, although he was already leaving anyways. Grif watched him turn around and walk away, torn between feeling sad and angry.
Anger won. "Fine then! Fuck off! Not my fault you're an oversensitive prick on top of being weak!" He screamed, storming off in the other direction. Only when Grif and Simmons were each sure the other couldn't see them did they allow themselves to take deep, shaking breaths and blink back tears beginning to prick at their eyes.
