Sock Yarn?

Oh dear - more sock yarn has found it's way into my house. But this time - it sort of wasn't my fault. In fact, it was being a good consumer that did it. I finished my blue tank and had 2 untouched skeins of yarn left (@ $9 each). I went back to the yarn store to see if I could return/exchange them. Hurray! I got store credit. What else could I do but get a skein of sock yarn. No pattern needed, no plan needed, just beautiful, soft sock yarn.

I have a problem.
