Well, if we're being particularly fussy.....
It's because I've only got my phone for the internet, so it takes ages to write stuff. so I try and break it down abit so its quicker to write. Didn't I didn't realise you had 2 to have an A* in english to write on here. Hope that vocabulary was up to satisfaction for you ;-¿ 

There we go Dom

To be fair it doesn't have to be perfect, just comprehendable. I'm 21 and i hate 'txt' speak, it's just lazy! (i got two D's in GCSE

)

It doesn't have to be grammatically correct either!
Some people just get sick of trying answering questions that start "Yo my golf iz broked, doznt start pls elp me owt" If it's harder to understand the question then give the answer it's not worth it...
