I sit in the waiting room until T comes out and she follows me into her office. We start off with just a minute of small talk while we get settled in our chairs, then she asks me what I want to focus on that day. Sometimes I will go back to an old/consistent issue and sometimes I will bring up something new or something that happened recently.
Honestly, you would see a lot of laughing. I am a naturally goofy person and that doesn't change when I'm in therapy. I do use humor to deflect (although I've gotten better at that), but most of the time I'm just generally making jokes. T has a similar sense of humor so she laughs too, but she tries to keep me on track and not digress too much.
We often will sit in silence. Sometimes I will answer a question, and she will think for a while before responding. Or it will take me a while to answer one of her questions (usually I will immediately say "I don't know" and she asks me to sit and think about it for a while).
She looks me in the eyes a lot. When neither of us is talking it almost feels like we're having a staring contest. It used to feel really weird and uncomfortable, but now I'm used to it and it's comforting.
You'd also hear me being constantly self-deprecating and my T saying "Uh-uh. Try again." (Apparently "because I'm stupid" is not an acceptable answer.

)
Then when time is up she walks me out to the front desk and we schedule our next appointment. When it's scheduled she says "Bye Annie, see you then, have a good day!"
