Two or three years ago, my answer to the question was simple: “Because I have to”. It was a compulsion which I didn’t really want to resist. But today, I think I stumbled upon a much better answer. I did my wife’s nails a few days ago, and today, both the PT therapist and the dental tech she saw complimented her on them, and asked where she had them done; she told them. Later this evening she mentioned this to me and asked me how I was able to do them; without thinking, I replied that I was really a girl, I just couldn’t pass the physical. She wasn’t sure whether or not I was joking. Neither am I.
