When having your spouse help, why do they have that depressing smile above their head ? Does it mean they don't like it and you can't build hearts (affection) ? Also when you choose for them to pick up, what exactly are they doing ? When I choose pick up, all they did was walk around all day ! :(
It's same smiley - not depressing, just a way it is drawn.
If they pick up, they finding herbs and mushroom, whatever goes into "other" category (shipped automatically, you don't get to see it. If you follow them closely, you will see them getting a herb or two out of thin air - I seen it couple of times, lol
