I've had that happen too. I'm listening and then I think, hey what happpened to the high frequencies, they're gone! It's hard to judge what a poster intends sometimes. I used to never use smiley faces or write "ha, ha." But now I sometimes do because it helps put the words into context, like I'm being (or trying to be) funny. Also I avoid sarcasm, which I'm personally fond of, like the plague! It doesn't seem to work on my posts at all. So much for the digression... Ha, ha!
