I think, if you're not on a discussion board like this for many years, you will probably not use perfect grammar. I think it comes with lots of practice. I don't think they aren't smart or inept, I just think they aren't use to using the grammar they learned in school. 

Granted. 
 

But I was referring specifically to persisting in a single error immediately after one has been corrected. 
 

There have been times when I have been corrected on this board for writing errors. I have always tried to receive and implement the corrections graciously and cheerfully. It requires no great effort to do so. Just a bit of humility.
