She loves Dr. Bryan because she wants to be a dentist when she grows up and last year, he learned this little fact about her which prompted a promise between the two. Hobbit is to go to school, get good grades and graduate so that in 20 years time she can take over his practice. Dr. Bryan is supposed to take care of her teeth and have a ball with her, which he and his entire staff do at an amazing level. They all love her there because she is "full of personality", as they keep saying - all of the hygienists come and sit with her for a bit so they can converse about fashion (she wore her sparkly Jesse boots today), movies (yes, Tangled is definitely worth watching) and education (of course being a dentist is a fabulous choice). I love how special they make her feel and that she and Dr. Bryan have this great "deal" all set up.
Every time we go in, he asks if she has graduated yet and her response is always "Soon, Dr. Bryan... soon."
