Question of the Day!

So, I am one of the fill-in questioners; let's get this!

2 things - one, I have no idea how to make it look purty, and two, I am Australian, so I spell and punctuate differently.

What is a word that you constantly spell incorrectly? (And no, the word 'incorrectly' is not a valid response!)

A word that MS Word always underlines in red. It might be a random typo you always seem to do - I have a friend who types liek for like every single time - or a word your brain defaults to mis-spelling.

Me? Occasion. I have to concentrate or else it comes out "occassion". Why? I don't know! I am a really strong speller. I know it's spelt wrong and when i edit, i will pick it up. But when I write? It is so common I have auto-correct in Word set to change it instantly...
