I should have added that in addition to his locksmith work, my in-laws ran a marine products business. They had the Australian patent for a product called Permatrim - it is an attachment that goes on the bottom of outboard motors to help a boat plane better in the water. They were big members of the Sutherland Shire Fishing Club in Taren Point. While he would certainly give advice and do sales over the phone and also do some installation work if it was in Sydney, my mother-in-law basically ran the business, doing all the bookwork, sending emails, taking orders, packing up orders and sending them to all parts of the country while he didn't do any of that at all. Left it all to her. And he still expected all the housework to be done and his meals provided.
They did this still while they were in their late 70s and while my mother-in-law wanted to retire long before this, my father-in-law did not. And since his word ruled, they kept going. What she did would have exhausted me, I do not know how she kept it up for so long. Anyway, he passed away just over two years ago and she finally sold the business. Sad it took a death for all this to happen.
