The Christmas my mother was displeased

I think this is the best story about my parents, although there are many great ones.

In 1988 or possibly 1987, my father gave my mother all of the following as Christmas gifts:

1. A typical Texas Instruments calculator with a slide-on case.
2. A small calculator with metal buttons, fitted into a glass paperweight.
3. A calculator with an AC adaptor, which could print its calculations onto a small roll of paper.
4. A thin calculator that was part of a checkbook.
5. A calculator with tiny, tiny buttons, which was integral to a digital wristwatch.

I think it’s only natural that he got a second, matching wristwatch as a present to himself.
