I bought yarn.
It called its siren song to me, and I succumbed. The purchase had the feeling of being a mad spree, a bit of a fling, a wild fit of naughty something.
For a while Big E had what I called his "Forbidden Army of Super Secret Guys" in the basement.
He would come back from the gaming store with a bag, scuttle into the basement, and then emerge flushed and stealthy. "Oh, I didn't find what I was looking for..." he'd mutter to me on his way past me. Now it wasn't that he wasn't supposed to buy these Secret models, or that he was being reckless with money. I think it was the feeling of doing something secret or forbidden, like eating sweets before dinner or sneaking a cookie from the cookie jar, that made him do it.
I think we all crave a bit of naughtiness now and then, after all we really are quite good so much of the time...
