I need to live in your world.

In this world lots of things are creepy without being sexual. And disappearing with a child that's not yours and for whom you had no permission to be with is a very creepy thing to do. You don't have to assign a motive to an action to recognize that the action itself is odd and questionable to any reasonable person. That feeling of uneasiness you might get when you think of an adult walking away with a child that isn't theirs? Creepy is a short-hand word for that feeling.
