No. I'm serious. I understand that from culture to culture the lore has variances. I said as much. I said I understand the flexibility that various incarnations show. Did you take that into account?
By and large however, vampires, do have some fairly "set" rules when portrayed in tv, books and film ever since Bram Stokers. Those have been toyed with and tweaked but largely vamps have in all portrayals had commonality. Frankly the vamps of Twilight barely appear to be branches of the same family tree from other vamps of the last 150yrs in culture reference.
