Ski Diva Extraordinaire
Thought I would throw a variant into this equation: What if friend IS an instructor, and certified? I can only speak for DH, who, while not currently teaching, can somehow go into third-party instructor mode if/when asked by skiing friends onhill -- i.e., "I feel off-balance, what am I doing wrong?" "Is there a better way to ski icy moguls, can you help?" I've seen him give 30 second tips that have really helped others (including myself). I know this is kind of an off-shoot, but this seems like a more acceptable alternative. I haven't seen him teach a beginner in decades, however - horse of another color. Also, my son taught us both to snowboard (also an instructor and certified) and was also able to maintain the "distance." We both got 1 hour privates. DH got it but didn't like it. I stunkWe both quit while we were ahead!
Since this thread is about beginners I will answer from that point of view.
I have seen other instructors TRY to teach their SO and fail.
I can not tell you how many relationships I have saved over the years. I was always the go to instructor when other instructors tried and failed to teach their SO to ski.
So my advice to other instructors is to pick out one of your fellow instructors to teach your SO to ski. Your relationship will be a much happier place.As far as getting pointers when you are a more advanced skier goes, that can work if you can take their criticism. If you can not then don't do it.
My husband and I are both instructors and we actually teach each other. I also taught him how to ride horses. It works for us because we both repsect the each other's ability to teach.Thank You Divas for your support of this thread. I thought long and hard on what to say without actually teaching. My goal is to get good information out to new skiers so they will go try skiing for the first time and have fun!!
We both quit while we were ahead!
I just want to keep this up high, especially now being a vacation week.
I did not stick around to see the out come. I have seen several skiers in the same boat this week too.
That was not a happy moment--I still married him, but that first ski day was pretty dicey.
This is suppost to be fun!! 
I can't imagine how terrifying it must be for someone to find themselves at the top of the mountain because a well-meaning but clueless friend or family member told them they could do it, or they should tough it out because that's how he or she learned how to ski.
She was very grateful for my help. She said there was no way she would have gotten to the bottom without my talking her down. I was able to tell her what to do every step of the way. Her boyfriend had no clue.
