I dunno, that feeling when you see someone you like romantically, that elation? As much as I love my friends, they don't make me feel like I have butterflies in my stomach and make me blush like a teenager, they don't make me want to cook romantic meals for them, I don't want to cuddle with my friends under the blankets while watching a movie or anything. I want to do all those things with someone I'm romantically involved with.

Also I give people I like romantically way more "passes" on unimportant stuff than my friends or family. Like they're allowed to get away with small things I'd never let slide with friends. Like if a friend wants to do something silly, I'd tell them to go screw themselves. But if someone l like romantically wants to do silly stuff, I'd entertain it. That's just an example. To a point of course, you need to respect yourself and all that.
