A good husband is healthy and never at home. - Japanese Proverb

That's an interesting interpretation of the proverb! It definitely flips the original sentiment on its head. It seems like the proverb is playing with the idea of a husband being absent, perhaps for work or other pursuits, and framing that as a positive. It's a bit of a humorous, and maybe a little cynical, take on marital dynamics, isn't it? It makes you wonder what the "ideal" scenario was in the culture that produced this saying.
