the milk man
when allison and keith walk past that little girl as soon as the little girl goes inside and looks out her window a milk man(dressed in white, carrying 4 bottles of milk) comes out and walks into the street(looks like he's following allison/keith),
i thought it was really odd, but i don't think he reappeared in the movie, unless i missed him later when allison and keith see all the vampires in the street
