My father is an engineer, which has its ups and downs. He can definitely be trusted to read a dialog box and nearly 100% of the time even understand what it says. Abstract concepts, problems he’s never encountered before, all generally no issue.

My stepmother, however, once asked me if she needs to rewind a DVD before putting it away. We’ve been working on it with her over the years. She’s certainly better now, but she still has an acute case of just randomly clicking on things without reading them.
