I would not make that mistake again.

I have had to sit with my own part in this, because a father who tells this story only as a rescue is lying by omission, and I promised David I would never do to the truth what Selina did.

The truth is that my son slept in a car with my grandchildren for weeks, and I did not know, and the reason I did not know is that I did not look.

He told me everything was fine, and I let everything be fine, because I am a busy man with a business of my own and a comfortable belief that my competent, successful son had his life well in hand.

I did not fly out unannounced when his voice went strange on the phone.

I did not press when his visits home stopped.
