Once my wife said to me (when I was preparing to change a tyre on her car) "maybe I should learn how to do that in case I ever need to". "Sure", I says. So I gets the wheel brace out of the car, apply the handbrake, and explain to her that it's good to loosen the wheel nuts before jacking the car up. She's very interested so far. I kneel down to remove the hubcap, and no sooner does my knee touch the ground than she says "oh, no I don't think I do that, I'll just call the RACQ!". Guess she didn't realize that it might involve touching the ground or the tyres!

For all that, I'm always happy to help someone who's stuck with it, male or female. Once got stuck myself with a crap wheelbrace and over tightened wheel nuts, when a bloke helped out with a cross brace. Always carry one in my car now.
