Make sure you have legal cover for what you're doing.

You don't want to be with someone who is already not getting from you what he needs emotionally.

The most reliable ways to make oneself miserable are attempting to change people and not attempting to change circumstances.

When you fail to see something, that doesn't mean I'm hiding it.

It's okay to forgive yourself immediately and for good.

Of course the thoughts and awareness are there, but it's all incomplete and often fanciful - kids know there's something to know, and they fill in a bunch of the blanks with their imaginations if their parents haven't had the conversations and/or established themselves as sources of information. It's rare that the kids know nothing at all, and the somethings they do know are often only partially right or flat-out wrong.

The only answer that has any chance against against the information saturation kids face these days is to talk openly with kids, early enough and often enough and unflinchingly enough that you set the precedent of being the safe place they can go to ask their difficult questions. It has to happen starting when they're 2 or 3, and they ask you where babies come from and instead of freaking out and deflecting, you give facts commensurate with their ability to understand.
