I didnt get what you're trying to say. What's one to do then?
GP gives a hint:
> You haven't changed your behaviour at all.
TLP[1] said it best:
> There you go again, thinking about yourself. Your impulse wasn't to say, "am I doing this to my kids?" or "how will I act differently?" It was to wonder about your own nature.

Although, this does fit quite well too: "I don't want to be with someone who doesn't care to drink tap water."
Anyway, not saying you said it was the same as the DSM definition, just adding some perspective since I read a lot of TLP and naturally compared what I read in the OP to what I remember from TLP's blog.
