In the past two weeks, I have replaced an old windshield (windscreen) wiper, replaced a car battery, and diagnosed and replaced a bad fuse. Therefore, I am going to consider myself a fully qualified car repair person/thing-y.
Being unemployed and needing to do these things for oneself can be quite gratifying. The doing-it-oneself part, not the being-unemployed part. Given unlimited funds and leisure time, I would learn mechanical repair, as I love to make things go right.
I have a warped brake rotor on the front end of the car (it's apparently been spending time with my sense of humor (humour), but it may be more than I can manage on my own. It is not unsafe, only annoying, so until the cash for two new rotors falls into my lap from somewhere, I will deal with it.
Meanwhile, I can add minor car repair to my resume (CV), as well as translation skills from American to English!
