Even I doubt if there is something like an SMS day. I just assumed that there was one even though there was no mention of it in that article.
Even I'm not used to SMS language and that was the reason the thread above turned out to be so horrible. I was in a great doubt with every word as to what letters have to be omitted and what letters shouldn't be. I think that I need to read some online tutorials that would teach me the SMS lingo.... I wonder if even that has some rules of spelling and grammar.
And, I also rarely use SMS as a means of communication. At times, I do reply to an SMS with a voice call. And if I reply through the same medium, I make sure that my message is 100% correct in all aspects: spelling, punctuation, grammar and everything else..... a futile attempt to make them stop using that modern day language.
