Quote: One of the key problems: there are no cars on Venus
Ah Venus and the art of Car maintenance. Yes it's a bit hit and miss among those I've known. But the other side is that while my Venus thinks car maintenance is filling the tank she will be worrying about how I maintain myself, and given that I don't do enough self maintenance that's a good thing. There's only so much maintenance worrying that one can do so worrying about me and a car or two is more than can be expected.
It's also about what the youngsters get to know and do in the early years. One daughter went surfing, the other came flying and driving. I was keen on all of those pursuits so yes, we reap... And I now have a daughter who is a better surfer than me and another who can fly (almost) anything with wings and drive anything with wheels better than I can. And that's ok.
This doesn't address the issue posted by Hannes but I suspect he knows the answer to his own question and would not have it any other way.
Venus maintains Mars so that Mars can maintain the cars. Well, sort of.
