Nope, on the internet, I don't talk anything like I do in real life.
I am really, really bad at speaking. Somehow it's much easier to write, the words don't get all jumbled and lost...
When I'm speaking, I forget words constantly and then I have to search for them and then if it happens many times in a short while I just give up in the middle of what I'm saying and leave the sentence unfinished...It's odd that it doesn't happen when I'm writing. Or thinking...just when I'm talking. Obviously it is annoying to others when I don't finish my sentences...And I mumble and speak quietly and unclearly. I can speak louder with family, though.
Aaaaaand I don't talk this much. By far. When I write down things like this stuff just springs out and it goes all off-topic and I end up writing about things no one would even care about. I wouldn't even dare to talk about anything I've said on this message board, either. About anything. Expect maybe my very first post which was about WoW, as my brother and cousin play the game. But they don't approve of talking about anything else but computer games. Cross the line and it becomes awkward.
The way I write on the internet does annoy me too, though! It just comes off as very juvenile and ridiculous but I can't write any other way, it would feel unnatural (when talking on the internet, I mean).
The name of the thread made me think of acronyms, so I'm going to say this - I actually say "lol" irl. And some other acronyms too.
