A brain in holiday mode

Something was very, very wrong in the longies pattern I'm working from at the moment. I'm slightly pissed, at the pattern and at myself.

"Work down leg decreasing one stitch each side of marker every 1,5 cm 22 times. When leg measures 14 cm change to ribbin."

Guess how long it took me to figure out something was wrong... I guess I'm sort of lucky; it was after 14 cm and not after 22 decreases. Now I have not been able to knit anything for two days, because I can't decide wether to fudge it or frog it.
