snipped

Strange thing is that I used to be a sailing instructor and was
considered a very good one. I used to take people (girls) who had
never been in a boat before in their life out in Solings on Sunday
afternoons in Boston Harbor and talk them through setting the
spinnaker (yes, I was young and dumb then). Everything seems to work
better with non-family members. A lot of this is normal family
dynamics spilling over onto the boat.


Roger,
That's because a stranger will give you the "benefit of the doubt",
kids just don't give it to parents. :-)
