I'm a desperately flawed being. Even though I've tried to do my best to overcome the worst of my personality quirks, every once in a while I'll just trip myself up and land splat! back where I started. Don't you just hate when that happens?
My worst, most fatal flaw is to say exactly what I'm thinking at a given moment, regardless of the situation or the need for tact. Usually I can slam the brakes on my tongue before I say something really appalling, but sometimes things just slip out and elude all attempts to catch them before it's too late.
I feel bad because I messed up big-time today. I said something really mean and sarcastic to Greg, even though I knew he was having a really bad day -- so in essence, I've just kicked the poor man when he was down. Of course, I've asked him to forgive me and he will, as always, but I just still feel very guilty about it. He never says such things to me, in spite of the fact that I probably richly deserve them. I just wish I could keep my big mouth shut sometimes. Of all the people on earth, he is the last one who should be at the receiving end of my thermonuclear slips of the tongue. Luckily for me, he is both understanding and forgiving.
