The lunch had been arranged after I had telephoned him out of the blue. I had reached a certain age, was thinking about starting a family, and was beginning to wonder about my own father. My mother was very supportive; she knew that it was something I had to do. Dialling that number, it sounds all too predictable to say that my hands shook, but they did. Suddenly, after a few rings, there was this voice, smooth, educated. My dad. If he was surprised at the approach, he didn't show it; instead, the date was arranged. I put the phone down.
