You know what really grinds my gears?
People who use the line, "I wanna say". Know what I mean? As in, "I was at the theater at ... uhh, .. i wanna say .. uhh .. 9 PM?".
Dude, if you "wanna say" 9 PM, then why don't you just say it? Wait a minute, you ARE saying it. Then what's with the "I wanna say" crap that you prelude it with. It sounds affected and annoying - and wherever you picked it up from, it isn't making you sound as cool as you think it is. If you're not sure about something, you could say "approximately", "nearly" or "I'm just plain daft", don't fake it up with "uhh I wanna say ...". You sound like Big Moose, dumb and delirious.
And that's what really grinds my gears. Tom?
