A lot of the times when I'm reading email at work, I'll notice people abbreviating words that are already short to begin with. Thx—short for thanks—is a biggie, and once I saw a CIO dude sign off on an email with TTFN (which I later found out was short for ta ta for now, haha!). Just when I think we're getting a little too abbreviation/acronym-happy, my cousin Nathalie will slip one of the above abbreviations into a conversation. They always make me think of food and crack me up every time. Do you use any of these?
