Ninjas!

I have a few minutes before I leave the house to go have a cup of coffee and do some reading and writing at the local coffee shop on my half day off. Just me. No wife in my space. No daughter in my space. No to-do list. Sometimes, particularly when I have a half day off, or come in late after breakfast, I feel as though I'm somehow being lazy, as I could be doing something productive. But then I'm at work, like I was the first half of today, and I hear over the wall of a cubical I'm walking past, "What IS that? Is that some sort of assassin ninja?" and I feel all super productive again.
