I usually say the worst things at the worst times, so I'm not much of a thinker before I speak. Like, blurting out something about my siblings infront of my parents, and then they would get in trouble and I would get in trouble after for not keeping my mouth shut. :x Usually this is the reason why I get in trouble a lot, and I feel bad after, because with logical and rational thinking, I could have stopped something that had caused a massive amount of damage if I had kept my mouth shut. :x Though now I do try and think before I say anything infront of my parents or any one else, since it's important to respect the decisions and well beings of others. Because like the old saying goes, the truth does hurt. So it's best just to not say anything at all and leave it.
Though with typing, I think it's more of a grammar issue I have, and that I do think about what I say, but I make silly grammical errors, and I should really learn to read over my posts. XD;
