Hiding

So here's a question I'd love to hear your thoughts on:

Why do we hide? Why is it almost always our first reaction to sin, wrongdoing, etc? Why do we think it will even help? Why do we think we can actually stay hidden?

Adam and Eve did it. Annanias and Saphira did it. David hid for a while after the whole Bathsheba incident. I would say even Judas tried to do it. And all of them got pretty messed up in the end.

So what do ya think?
Can you think of any other "hiders" in the Bible?
