[...oh no! You've been stomping on his culture this whole time! No wonder he's being so cranky with you, good job egbert, why don't you just make fun of his horns while you're at it! Okay, they're pretty nubby and cute and you'll probably tell him that just to annoy him but that's not a culture thing, that's a personal thing! Totally different things!

Whoa, you are totally right! Gosh, Karkat, I'm really sorry, I've been being very culturally insensitive! Just because we're bros doesn't mean you're automatically going to trust me. I guess we're different about that kind of thing!

[You feel like a huge jerk!]

But maybe in the future you'll trust me a little more okay? I'll stop pestering you. About that, anyway. You can't make the prank master stop pestering about everything, hahaha!
