Kill Code

"The code you have entered is incorrect. Please try again."

I stared blankly. I reentered the code.

"The code you have entered is incorrect. Please try again."

I sighed, silently cursing modern technology, but not too hard as I knew all the positives it gave. I retyped the code, comparing it against the one I wrote down, and hit enter.

"The code you have entered is incorrect. Please try again."

I looked at the time, then in desperation looked again at the code, then replaced the zero with an O, getting in just in time to see the first killing.
