One of my biggest pet peeves is when people don't write in complete sentences while texting. It's so annoying. Well obviously it's not my biggest pet peeve because if it was, I would be constantly screaming because everyone does it.
I also hate abbreviations. I mean that I hate them in texting. I have no problems with the FDIC or the FSA (I'm learning Alphabet Soup, forgive me). I have problems with those texting abbreviations because then I have to look them up.
I just learned an abbreviation today from my mom. That abbreviation was TBD meaning to be decided. I feel so cultured when I don't know what a texting abbreviation means because that means I don't use. And if I don't use it, that means I'm not completely destroying the English language with meaningless gobbledygook.
