i don't think that there is anything about me that someone doesn't know...seriously. and, there are a couple of people that know pretty much all of it. as i've gotten older i just don't have much of an ego anymore, and the list of things that i did (or didn't do) in my past, that i still feel particularly uncomfortable or ashamed of is pretty damn small, and i think i've divulged pretty much all of them to someone.
one thing that i recently realized...if you set out on a course to eliminate regrets, you may very well end up with some bigger and more pervasive regrets than the innocent and childish regrets that you replaced.
heck, sometimes you might even find yourself wishing that you had the old ones back.
