Thankee for explaining for my laughing comments for me, Huz. Methinks (
) that you folks need to drag Jackal and Jelena into the AG IRC channel at some point.
Anyhoo. I admit I tend to use "heh" a lot myself, just because I need to acknowledge I was paying attention to something someone said, but I don't have a "real" response to give.
For me, "ah" indicates understanding, "oh" indicates puzzlement, "hmm" indicates thinking, "mmm" indicates feeling displeased/disagreement, "hah" indicates amusement, etc. One starts running out of ideas for what to use for just a plain old short and completely neutral acknowledgement.
(Yes, I actually think about this sort of thing. I prefer to be as precise and consistent as possible in my use of language.)
As for text messaging... I just don't get it. If I wanted to talk to someone right away, I'd call them and talk to them. If they weren't available, I'd leave a message on their voicemail (let's face it, anyone who has SMS probably also has voicemail, at least with US cell phone packages). If it could wait before I contacted them, I'd write a proper e-mail or IM them.
I can't think of any situation where I'd want to send a cell phone text message that's short and expensive, and I have to type on a device not designed for it, and I likely won't have enough room to get my complete point across without resorting to abbreviations... yeah. But then, there's a LOT of popular stuff I just don't get because it just seems very impractical to me... *shrugs sheepishly*
Peace & Luv, Liz
