Now, I'm okay with "lol", "gtg", "brb", and that stuff. But please, PLEASE, do not use "u" in the place of you! It's REALLY hard to read a sentence, let alone an entire paragraph, when half the words are just a single symbol that is a mockery of the actual language!

Saying "lol" is okay, because it's separate from the sentence. I'm even fine with the occasional "idk" as long as it's just an addition to the message. Just, please don't use abbreviations in the main text! Use them as an add-on, like emojis.

I prefer speech-to-text rather than an alien trying to sext.
