They are all so different from each other aren't they.
I think the difference can really pop out at you when there was one that you are/were so close to. It just makes differences that much more apparent.

I would likely have the same issues with the differences between any other dog I get and Molly. She was such a diva.

I know you love Sibbie and she knows it too. Jut she is who she is. I think she is probably has the potential to be the boss of the house.
