(Either that, or she doesn't know you're alive, her thumbnail is bugging her, and she's biting it off.)
He's hungry
You have startled the dog..scared him

When a man bites my neck, it's an instant turn on. I mean, right now, find a bed. It took me a few years to develop this, as a young woman, I didn't like it. The older I got, the more I enjoyed biting, and being bitten.
it means he legit likes you a lot and wants to stay with you for longer than you probably expected
They like you
She's either concentrating, is nervous, or is teasing you.
it depends.. It could mean shyness or boredom or it could just be a habit ;)

what does the phrase rule of thumb mean
he wants to kiss you ;* no joke, I really think so...but I'm a girl (: And if he bites his lip, that's a plus! go get 'em girl! ;D bahaha
