I love when Bella does all the things that you mentioned above (especially "making her bed"). I'm 22 and she is definitely the closest thing to having a child for me...for at least the next few years.
Another super cute thing that Bella does is use her little front paws as hands. She loves to lay on her back and chew on her her favorite little Nylabones while holding them with her "hands" and I LOVE it!
