Cheating partner!

Well, I thought the agreement was that I did the planning and my partner bought the groceries. But when he saw the shopping list, he bailed out! First he complained abaut the length of the list- well everything is on it, so there is no need to think in the store... and eight meals actually require some ingredients! And then he asked how we would find storage for everything. And finally, he refused to go shopping alone. It was nice with the time together, but no time is saved.
