They surfaced from the kiss, Bella panting. Edward (in his oh so vampirish way) was absolutely fine. Eager to get him to respond to her kiss, Bella dived in for another. She nibbled on his lower lip...

Big mistake

"ARGH! MY TOOTH! WHAT IN THE WORLD HAPPENED!" (Yes. Bella CAN speak in multiple exclamations) She held a hand to her throbbing jaw, blood dripping from the corner of her lip. "Is your mouth made of stone or something!" She pointed her free hand accusingly in the vampire's direction. Edward seemed occupied with the blood running lazily down her lip, red had enveloped his usually topaz eyes. He seemed to be refraining from licking his lips. "Edward?" 'Maybe I should get angry at him like this next time, it gets a good response.'

Then she realised. (A very Bella thing to do)

As she'd been talking blood had flowed freely down her chin and, like rain, dotted the pavement between them. "Great! Bloodlust!" She grumbled, wiping her bloody chin and scattering blood even further afield. Edward now had a hand over his nose. He stepped away and ran. "Oh perfect! Now how am I supposed to get home!" She yelled at the fleeing vampire. She kicked out at the path, catching the car key Edward had left and sending it pin wheeling across the pavement. A note was attached

Dearest Bella

I'm sorry but the blood dripping from your lips has caused me to have an extreme need. To kill shed loads of cute and fluffy animals. I may be gone some time so here are the car keys. I'm sorry; you'll have to drive yourself back. Drive safe and wear a seatbelt.

Edward
