While I'm up...
Just the other day I was shouting at my computer because I couldn't figure out why I'd written such nonsense. No, it wasn't a piece of text, it was just one word: type.

My brain just couldn't accept the fact that it was an actual word, it either didn't exist or was spelled completely wrongly. I'd just been doing a find and replace in my code to change a variable to be called type, so I knew it was right 2 seconds ago, but now I was having an argument with myself and my computer about why it was lying to me.

I seem to recall that this isn't a new thing either, I remember asking my dad when I was a wee nipper, what this strange word "ancient" was, despite being old enough to know better.

I often do this
I'm a pretty decent speller, but occasiionally I'll write a word and it just looks "wrong". Weird.

And
in fact did it this evening, read the phrase "Cancer of the Intestine" but somehow kept reading Intestine as In-tes-TINE. Odd.
