pride goeth before a frog

One should never knit really, really late at night, a lesson I re-learned this morning when I unsuspectingly picked up my second nereid fingerless glove. I took a glance at the pattern - I'm on the third row of the first chart. No worries! Away I go...

... but something's not right here. My ribbing is out of time with the pattern - sort of. In fact, the location of my ribbing is alternating with every repeat. What's gone wrong? And more importantly, why didn't I notice last time I was knitting on it, i.e. before I would have had to painstakingly tink three rows?

Sigh. I'm not sure how I failed to notice it. I'm pretty sure the problem is that I forgot to do the pattern set-up row after the ribbing at the bottom. Why? Well... I wasn't exactly reading the pattern. I mean, my first glove came out perfectly and I have the chart memorised, so why would I? Yeah, that's why I shouldn't knit late at night.
