"Well, it should be pretty obvious, shouldn't it? I mean, I can tell Autumn doesn't like me, but she loves me, y'know, 'cause she has to? But I can really tell when I'm annoying her."
She looked thoughtful. "And if I'm feeling generous, I'll back off."
Brenna shrugged, glancing around. "I dunno. I asked my mum once when I'd know if I was in love with someone. After she decided I shouldn't be in love with anyone 'til I was at least eighteen, she said you'd just know. She said you like to hang out with them, and spend time with them, and that you think about them a lot, and when you have important news, they're the first person you want to tell. Stuff like that."
Her nose wrinkled briefly. "Guess I'm lucky. I haven't gotten all obsessed with anyone yet."
