Seriously, all they do is repeat a line over and over. They claim to have a store...where is this store?
She keeps it in the same magic knapsack where you put the 300 pounds of loot you hauled back from your last adventure.

I would also like to see my wife out in the marketplace, I wouldn't even care if she didn't say anthing while shopping.
Thoughts?
I usually only marry NPCs who are also followers so having them do nothing but wander around the house for the rest of my game is not an issue. But I agree that it would be nice for spouses who are left at home to be able to leave the house and have a regular schedule of shopping, visiting a local temple, the inn for a drink, something.
