why dont i learn?

why have i still not learned how to just keep my mouth shut? honestly its what gets me into the most trouble. I ask (i guess unnecessary) questions at the wrong time and it just makes things go from good to bad...on top of that i try to explain stuff i do or say/ask and it just makkes things go from bad to worse. ugh, i guess i'll learn soon enough...or at least i better, after all it is what causes most of my problems. im not saying that i have a big mouth when it comes to other peoples business or even my own because i know how to keep a friends business a secret if it is intrusted to me, but for myself i think i might be better off missing that part of my anatomy sometimes...would definitely make my life a lot easier is all i'm saying. whoever said curiousity killed the cat was right, maybe not to that degree but dang near. i guess i'll learn...eventually haha
