I wonder if the emotional by default is more akin to us lady folk *ducks for cover*. I agree that as long as the tree bares fruit (good soil, enough rain, and sunshine) it is a tree I would like to have also.
Good luck with your plan. I like your thoughts on the "upgrades" and "engine". I see that upgrades are OK if we can manage to ensure the engine still works, is not interfered with.
