Loose/Lose and other idiocies

I understand the fact that we all make grammatical errors, as very few of us are English majors. We also usually don't want to take the time to proof-read everything we write to ensure that it is 100% grammatically correct.

However, there are some errors I see consistently that makes me wonder if people ever made it through the 4th grade!

A prime example is with the word "loose". More times than not I see people using the word "loose" when they mean to use "lose". It's as if they don't even know that the word "lose" exists! They will write something like "I hate to loose a game." Or, "I hate loosing." Come on people! It's "lose a game", and "losing"!!!

While we're at it, what's with the improper use of "there" instead of "they're", or "your" instead of "you're". Just gotta love it when you see something like "There going to the store" and "Your an idiot". Sheesh!

Do these people truly believe that "your" can be short for "you are", or "there" for "they are"? If so, we need to send some of them back to school.
