What were the vampires actually doing for most of the time?
I mean, the time that the humans weren't making themselves easy targets. Did they not realise where the humans were hiding? Clearly it didn't occur to them to make a methodical sweep of the town. Is there a deleted scene explaining that these days were spent styling their hair, ironing their clothes and practicing their scary growls? Could they not also have spent an occasional 20 seconds wiping the blood from their *beep* mouths?
