I'm So Psychic

My fiction workshop professor told me to start writing and keep going until I'm done. It's my thought process that's blocking me, she said. So I tried this method this morning. I wrote tempature. Tempature!
"That isn't a word," the red squilly line underneath it told me. "Try again."
So I did. I tried again and got temperture.
"Wrong. Ha ha ha ha! You speak English funny!"
That damned squilly line. I gave up and clicked their suggestions. Temperature.

Is there something wrong if I can read my computer's mind?
