I just chalked it up to the amount of times they got screwed over by people of lower ability, so in general, there was a lot of defensiveness. The male-role thing was apparent, but after earning respect and trust, they pretty much always got out of my way.
I've had, quite often, jobs where I was more or less helping the home owner build and those were the most enjoyable and memorable moments. Contrary to what this story suggests, it was usually the rich folk who got on their hands and knees beside me and pounded nails. I think it was about perspective. The rich folk seemed more willing to learn it, try it, and logic out the problem. The middle class folk didn't seem to willing to learn or want to get their hands dirty, so usually they weren't present and were more prone to complaining.
Construction is super easy if you can think about the problem from multiple perspectives. I find it surprising how few people have the capacity to view the world in this way.
