The major problem in texting is the abbreviations, such as "u", " gtg","ttyl","lmao" and so on. These abbreviations cause improper grammar. Those who use these abbreviations, instead of using proper grammar, get into the habit of using "u" and "gtg" and then when they write a paper, or reply to an email, or something they end up using those same abbreviations. Causing a deterioration in proper English usage.
