After years of seeing people write 'lol', 'ttyl' and a host of other texting/messaging acronyms, I just have one thing to say.
I'm not hearing what you're trying to say.
When you write 'lol' I don't hear you laughing, I hear you saying 'l,o,l'.
When you write 'brb' I imagine that you must be cold, not that you're going to be temporarily unavailable.
And the worst one, not that we can blame this on messaging, is RIP. There is nothing restful or peaceful about the word rip. Especially when it's in all capital letters. If you're genuinely upset about the passing of a loved one or public figure take the time to write out three little words. I mean really.
That is all.
