Generally less intelligent/educated than those who don’t? Or just lazy?
Things like:
It will b gr8 2 c u! Thanks 4 bookin it lol!
Sometimes see this on social media and it grates on me as it’s so easy to spell correctly nowadays and how much longer does it take to type ‘You’ instead of ‘u’?! I also don’t get every other sentence ending with ‘lol!’
