BM it's just my opinion from things observed, no big deal as they are grown and can do what they want! I just hope that you honestly don't believe that all they do is go out shopping. The shopping gets done in the last few minutes before getting back to the apartment. I mean, how long does it take to pick up a flat of eggs, a head of lettuce or two, a loaf of bread, water, tomatoes, and the few other things they always return home with! I agree that some days they go straight out and shop for groceries and then return, but the days they are gone for hours I seriously doubt it!
