Hi Carolyn Joy,
A man I worked for as his gardener had slit pupil eyes. Let's call him Mr R. They were shaped exactly like a cats eye jewel. Both he and his wife were of upper crust English extraction, and were considered to be Yankees, or WASPS, here in the States. At first I was just a crew member in the landscape company that mowed and trimmed for him. Later, I was hired away from the company to become his gardener. After some years had passed, and there had developed mutual trust, and even fondness, both Mr and Mrs would often drop their usual, cold, impersonal manner, and though always correct and understated, would talk to me with a lot of warmth and near comraderie.
Now I'll finally get to the point. Mr R's eyes had been the subject of a few conversations between us and there had always been something that seemed to be understood, but not mentioned at the end of the talks. For instance, Mr and Mrs R would often gaze at me after the words of a conversation were finished, as though more could be said, but would not be. Finally, one day we were talking about why, after many years of marriage they had not had children, but did have an adopted son. I had always assumed it was that one or the other of them had had something physically wrong as the reason. Mr R told me that his eye shape was reptilian, not of cats. Then they each said that somewhere in each of their respective families were individuals who were "off", and so, in the spirit of "doing the right thing", they had decided not to have any children, though they were able to have them.
The point I would like to make is that even though Mr R had reptilian blood, or genes, he also had a conscience and good moral character.
