Talk about a brain fart!

I've finished the bottom ribbing and began working on the first sleeve, using DPNs. I am not all that familiar with them - only used them one time before. But I felt comfortable. That is, until several rounds into the thing I came to the end of a needle and wondered where the now-empty needle was. Wasn't in the knitting, not attached anywhere, not on the desk or the floor or lost in my hair. I panicked - where could it have gone? When would I be able to get another one? How would I manage to finish my sleeves, and could I really use a spare DPN in a different size, like I've read about before? Worry mounted, anxiety increased, and I felt totally stupid. And then, I felt even stupider, when I looked down and saw it, the empty needle, resting idly in my left hand, waiting to be transferred to my right hand to begin the next group of stitches.

What a bozo...
