I'm not a fan of dirt under my fingernails, or even the sensation of dirt on my hands at all. But there was time, not very long ago, that I walked around with dirt on my hands, just hoping no one would notice it. I knew it was there; I knew why it was there. But I definitely hid it from everyone. The last thing I wanted to do was talk about what I had been doing (or not doing) that made my hands so dirty.
