LOL! I can understand that. Admittedly, I’m not in the mainstream of socialization, but it seems to me that exchanging friendly text messages takes an association out of “working together politely” and into “personal interaction with room for development.”
I have an age-related aversion to using abbreviations, even when texting, although I’ve assimilated “K” and “pls.” The only people I text are my husband and my hairdresser, and my preferred colloquial signoff (if we’re going to meet) is “Seeya!”
I don’t have that issue at all — I just don’t text. I hate my touch screen phone and thus just don’t do it!
