"teaching" your significant other
Being an instructor in a relationship can be fraught with peril, especially if you, yourself, are not truly an expert.
I taught my wife to drive a manual. She actually enjoys it now and prefers a car with a stick. But I was a car FANATIC, followed racing, could effortlessly do heel and toe downshifts, and generally knew more than the average schmoe. My knowledge was more than adequate and I had the patience to work with her.
My ability to teach her sailing is not nearly the same thing. I just don't have the proficiency myself to teach her. When we get our boat (completely ashore at this time), as our experience grows, I know she will add to her repertoire of skills, just as I will.
