During the summer time, my therapist will often wear skirts that are shorter than usual for her age demographic, along with open-toed heels. Now maybe it's just my imagination, but it seems like when she wears this attire--which she wears very nicely, in my opinion--she becomes more "girlish". It seems like she moves around more and becomes more expressive. I like this side of her, but I do admit that sometimes I'm like, "My, aren't we Miss Chirpypants today! Simmer down now!"
It seems to me that my therapist has two "professional" moods. One is upbeat, talkative, yet attentive. The other is ultra upbeat and ultra talkative, not so attentive. I'm sure she has a depressed, grouchy mood but she has never presented this side of her (at least not since I've been paying attention.) I don't think she's being inauthentic when she's hyper. I think she's just turned up a notch.
