The one on the left tells me she has a riddle to share:

One thing and only one philosophy brings the inner man free from violence and harm. It is superior to pains and pleasures. It does nothing without a purpose. It enables man to accept all that happens and all that is allotted. And finally to wait for death with a cheerful mind as being nothing else but a disillusionment of elements of which every living being is confounded of.

This is how she remembered it-as it came to her from a boyfriend. A Google search shows it's a (pretty close) quote from "The Philosophy of Antoninus".

Oh, and that's the dogs teddy bear. Which explains his concerned look.
