Watching What I Say or I Don't MEAN to Piss People Off

Sometimes I need to watch what I say, especially on this blog. While never meaning to abuse anyone's trust or anger anyone, I tend to say anything. Whether this is interesting, or tasteful is not something that always pops in my head. When someone says something to me that I find newsworthy (to me) and that something is a tidbit that I would like to remember, I write it down here. I consider this blog my journal. The only difference is that my thoughts are on display. I basically just sit down and type whatever comes into my mind at the time. Is it always something that I should write down? No. If it's something from my own life, it has no consequences, as I don't get embarrassed at my foibles or believe in locking who I am away inside (I've done that enough in my life) but when it is something from another's life I need to perhaps be more cautious. Applying my lax attitude towards my own life to others is unfair to those that might not want personal details posted online for all the world to see. Even omitting names does not suffice (although I might want to practice that come to think...) Now it's not that I don't think confidence instilled in me is a good thing, I'm just not always the best judge of what is supposed to be a close knit secret. For me, if someone wants to know something, I don't mind saying it... If that person wants to tell other people what I said/did, so be it. I guess my natural instinct is to just assume that all people are like that. Clearly they are not, as I have learned on a few occasions. Each of those occasions has come as a complete shock to me. In the future, if something even seems remotely like information that shouldn't be talked about in a "public" setting (let's be honest, I don't think too many people read this) I will either avoid mentioning it altogether or just ask first...
To the person who I appear to have offended, rest assured that it was in no way, shape or form intentional, and I think you should know me well enough to know that.
