Never show me your OCs because my OCs are superior and I will laugh at you in my brain for it AND I'll tell my therapist about you and we WILL laugh at you together. How dare you have the bravery and self-confidence to think your OCs are worthy of my ears. I've had my OCs for 3 years, how long have you had them? Aha, that's what I thought. Do you devote every waking hour to thinking about their development? Can you listen to music normally without thinking, "these remind me of my characters"? Do you write and rewrite their backstories constantly trying to get them perfect? Yeah, thought so.
I epically spit on you and push you off the grand canyon to your inevitable demise. "Perish, weakling. Come back when YOU'RE a main character." I cackle as you fall to your death.
