We all make mistakes Brocket, sometimes we may even not know how to spell the word, but it doesn't take a lot of effort to find out how to spell it.
What annoys me most is that people now days don't seem to care.
I tell my grandkids, regularly, learn how to spell and learn your grammar, because social media is not the only thing you will be writing on in your life.
Having said that, I'm not well educated, leaving school with no qualifications at 16 but I try my best!
