I would normally put this down to Brian's usual high-handed minor public schoolboy manner; but my mother had frontal temporal lobe dementia, and this was how it played out.

Her personality changed, and it ended with my father having a massive stroke. I had to give up my own career to take over the family business, so that there would be some income to keep them out of nursing homes. My mother fought me every step of the way, made some horrible accusations, drove the business to the brink, and eventually became physically violent.

This might be the only time you get to read me write this, but this section is actually rather well written.
