Forgetful

I'm currently at a sleep clinic and will be here all afternoon.  Every two hours I take a 20 minute nap with nothing to do in between but sit around.  I came prepared to get a lot of knitting done and had dreams of finishing the entire second sleeve for Leyfi.  I remembered to bring the sweater.  I remembered to grab the right needles.  I remembered the magazine with the sleeve chart.  Know what I forgot?  The yarn.
