You don't actually have to yell at me. But you can, if you want. I can't guarantee I'll take it well. You're yelling at me, remember?
Feel free to also speak softly to me, send me love letters (this makes it sound like I encourage stalking, which I don't), ask me provocative questions (when is it appropriate to wear sunglasses at night? answer: when you're a vampire or a douchebag, only one of which exists...) or just holler out a friendly salutation.
I promise I'll write back.
