Of any kind. Doesn't matter if it's on here, on other forums, on Facebook, on skype...I just hate it.
I just send someone a PM, and I feel I put my foot in my mouth. If I could go back and delete what I wrote, and rewrite it, I would...but I can't.
I've lost friends over this inability to edit myself. I just come out and say whatever is on my mind, on the internet. And that can be a dangerous thing, because people don't always want to hear what you really think.
