I can spell fine but when i text i usually use shorthand or 'text' talk as kitedemon said. On here sometimes i mix in a little of it too. Not bc i dont know how to spell, but bc i just dont feel like taking the time to make all my posts look perfect for you all lol.
For example in this post i didnt capitalize "i's", use apostrophes, and didnt spell out "because". Am i capable of doing all of that? Sure thing, i got a B in english last semester. I dont consider what i just did to really be that bad, but thats my opinion as a 19 y/o who grew up with all of this kinda 'text' talk.
Now when i see ads on craigslist that look like this, then even i get annoyed and can understand what you guys are saying lol:
