My best story comes from a rather well-known Pacific Northwest garden guy. He used to be on TV a lot, and still has his own line of seeds. Here he is, Ed Hume:

Ed Hume bio page)
I can't recall where I first heard that he said this, though I think it's rather brilliant. These are probably not his exact words, just my best recollection.
When pruning a tree you need at least two people.
One person up in the tree, or on a ladder, doing the pruning.
One person on the ground, looking at the overall shape as a guide.
These two people should never be husband and wife!
So yes, there can be challenges with relationships and gardening or permaculture!
