I personally know someone who writes like this. Messages, blog posts, emails, sms, anything. I see their message, mark as read, and move on. I simply can’t. My brain cannot comprehend this grammar (or, rather, lack thereof). Instead of consistently getting pissed at this person, I just don’t read what they have to say. If it’s truly important, they’ll tell me in person the next time we meet. Otherwise, it’s fodder in a seemingly endless maelstrom of random letters.
