1. After a while, you simply learn how to tell, and it is as casual as someone knowing how to brush their teeth. Usually, it is the scent that tips you off.
2. What kind of a silly question is that? What on earth would I be doing that would guarantee I would die in twenty four hours? I suppose, assuming that was the case, I would be doing whatever it took to delay my death.
3. The young ones must sleep at night, but the older you are, the more control you have over that. If you do choose to stay awake, you will begin to pay for, just as a human suffering sleep deprivation would.
4. It does not matter. Sleeping prey makes for an easier target as far as struggling goes, but they also tend to be more protected.
5. Right handed. Clearly, you are not observant to need to ask that.
6. There are a few. I have never met one personally, but I have met those who have survived them. Most are sad, pathetic creatures who could not find a vampire if it was attached to their arm, and if they do happen across one, that is the last one they find.
7. I happened to move here about three years ago.
8. No, it is impossible.
9. Very rarely. We are not social creatures by nature for the most part, though the younger ones still cling to their more human needs of companionship. There are a few covens, and there is a vampiric law, but for the most part, we nod politely and steer clear of each other's territories.
