I remember when I was 17 and had an essay to write. I decided to write a story and start with the classic ‘Once upon a time’. But I couldn’t spell ‘Upon’. U.P.O.N. Yes I was seventeen, and COULD NOT for the life of me remember how to spell a word that I had seen and read millions of times.
Then I conveniently gave up on the essay....till later.
Yes I will be teaching your kids soon enough.
Don’t worry it’s not how you spell it, it’s how you use it.
