An example between me and my therapist: our college teams are rivals. So when our teams play each other, we tease each other and do a little trash talk.

So to answer the question in general, yes, T and I tease each other. We both have a similar sense of humor, are both sassy and sarcastic. We get along quite well. I'm glad we can be lighthearted in therapy because it makes it easier for me. (And I do also use humor as a coping mechanism, and T knows that, and she helps me draw the line between joking around, and joking to avoid talking about my feelings.)
