I get grief for this but I refuse to use txt spk in texts and always use proper English (something even my almost 60 year old mum doesn't do anymore).
Im the same mate. I use proper grammar when writing a text (good job I get them free lol!) but I struggle to understand some of the gibberish. It's the whole using abbreviated words to explain things. Most people get free texts but yet can't write in proper english m8. lol !
