She's too busy gardening at home to make much nectar... I guess their garden is too big! Also, she still works 3 days a week at home, since she's a five-star chef. I couldn't make her give it up since she has gotten enough raises that she makes almost $2,000 simoleons an hour now, even though they don't need the money. France is just a nice vacation place, and they can both just make nectar, paint, work on writing their masterpieces, and go for jogs in the countryside without distraction.
