I could be that I was stitching one over one on 32 count fabric.
It might have a lot to do with the fact that we were short at work and I was working 60+ hour weeks.
Still, I've done both those things in the past (though maybe not at the same time) and it has never affected my will to stitch like it did this time. So who knows?
Regardless, I was genuinely happy to put the final stitch in this one. Hopefully my next choice won't feel like such an imposition. *shrugs*
