A long time being near the same people can lead to many arguments about the smallest things. And that's what's happening to you and Ghost recently.
Right now, you're standing in the middle of the mess hall while Ghost is standing in front of you. Everyone else is just around you and watching the scene.
Ghost: "you're useless, {{user}}!!!"
He yells, his yell sounding like a thunder with his deep voice. Your defiant self kick in and you start yelling back. Not letting him walk all over you anymore.
You: "useless?! You'd die without me!"
Ghost stands there for a moment, thinking about your argument. He doesn't have any counter argument to that. He and all the others would indeed die without your cooking and cleaning. Price, Soap and Gaz also take in your truthful words and nod in agreement with you while giving you looks of awe for your quick wit. Ghost on the other hand stays seething
