Spell Check?

I was gonna rant a while ago but I forgot. Here is a new rant.
First, I got destroyed and burned and destroyed again in my midterm. I guess instructor said spending 20 hours a week wasn't such a bad idea. I think I need more hours to do that.

Second, I may quit work soon. The management turns for the worse. I can't believe so many people are not happy with current management. It's the same person but it got worse. Shit is hitting the fan soon. I hope I can get out before that.

Finally, the relevant rant. I don't understand the English language very well. I was never a good speller but at least I use spell check on my words most of the time. Granted, it can't check right spelling/wrong usage of words; that's my weakness. With spell check so accessible, why can't people use it? At least use the proper grammar would help. I know mine is not in perfect English but it's still readable. Your and you're; there, their and they're; its and it's. I don't understand how people constantly mix these up. People use short form for ur is fine for textspeak or social media with limited space. Don't use that on Facebook. You can fucking write an entire essay on Facebook. Don't use textspeak. It's annoying and makes you look like you are uneducated.
