Too Tired To Knit?

It doesn't seem like knitting would take much energy, does it? But sometimes I am honestly too tired to knit. The thought of holding the needles up and telling my arm muscles what to do is too much, sometimes. Pathetic!

I'm excited too because I was commissioned by Husband to make him some thick warm socks, the night before last. It's such a treat to have a husband ask you to knit something for him (that he'll actually wear) that I'm keen to get them done. I actually have finished on all ready (yay, left-over black Wool Ease!) but this morning my arms are rebelling. I guess they need a rest.
