If you inspect a large and frighteningly marked spider in your kitchen and decide to take a picture of it so you can figure out if it is horribly poisonous, and possibly maybe a little bit also because you want to freak out your very arachnophobic friend...
...put a glass over it or something so that when you come back into the room with the camera IT WILL NOT HAVE DISAPPEARED TO PARTS UNKNOWN.
Because then you will have to realize that such mixed motives are very unkind and are very bad karma and will BITE YOU IN THE ASS. JUST LIKE A LARGE AND FRIGHTENINGLY MARKED SPIDER WOULD.
Going to lie awake and shudder now.
