Turn off your "Caps Lock" key. Yelling is rude.
Neither a spell-checker, nor a dictionary would have caught the error involved with the homophones "no" and "know." It was a proof-reading error and I believe it was confessed.
I'M SORRY I CAN'T SEEM TO FIND THE CAPS LOCK BUTTON...LET ME FIND SOMEONE PERFECT TO DO IT FOR ME.....
