I only shorten words like going to goin and you to u.
everything else I try and spell correctly, predictive text does it all for you anyway, it can take longer to abbreviate sometimes.
but I have a big hate for the text speaking kids now-a-days, they actually talk like that now, because the schools have become slack. I even hear that they aren't made to do P.E. anymore!! Back in the day we did about 4 hours+ per week. Which mostly involved running around in circles in a field in December, then getting your ass whooped by the giant kids at Rugby.
that's why the country is full of fat, illiterate, good for nothing lay abouts!
