My biological father gave me a car for my 17th birthday, then told my stepdad, “now he knows who his real father is.” — I wanted to humiliate him back, but then I came up with a lesson the whole family would remember.

And the two insurance certificates themselves, which I still have and which are the plainest documents I have ever been destroyed by.

They are A4. They are computer-printed. One is slightly yellow along the top edge where it has sat in an elastic band for a decade.

There is nothing on either of them except a policy number, a registration, a vehicle description, my name under POLICYHOLDER, his name under PAYER, and a figure.

No note. No message. Nothing written on the back.

And I keep going back to the fact that he filed them.

He did not throw them out. He gave them to my mother and she put them in the folder with my birth certificate and my exam results and a photograph of me at about four.

Which means that at some level that man expected somebody to look at them one day.

Not necessarily me. But somebody, at some point, going through the paperwork of a life.

Eight thousand nine hundred dollars and two and a half years of Saturdays, and the only record he left of it is two receipts in an elastic band, filed where they belonged, with his name in the wrong box.
