Just wait for them to slowly end up starving like in the movie day breakers.
Cover myself and glitter and start boning Kristen Stewart...
I'd improvise. It might be a little harder to destroy vampires though. Maybe I'll get a lot of glitter and pretend I'm a vampire then they'll all follow me as their leader. ...and I'll tell them to stand guard for the Zombie Apocalypse or teach them to be vegetarians. xD
I would hide. I would also turn my house into a tanning house yep all the lights would come on at night. An I would take showers In sun screen. It might be kinda interesting at first to see who all makes it by if I get bitten ill just carry out my life after death life. Maybe have a few neck biters myself lol!!! Jk
Now that would be awesome. I LOVE vampires.
