Too tired to knit?

I'm almost done with my Lacy Scallop sock #1, and Elena's first sock. I was really hoping after an exhausting day at work I could come home and just knit. Don't feel like it at all. I look longingly at the various projects calling to me from coffee table, night stand, end table, desk and think to myself, "I am too tired." Preparing dinner, that's what I need to focus on. And maybe tomorrow the knitting will happen.
