I got summoned for jury duty! I'm so excited! This is the first time ever in my whole life that I've gotten a summons, and I'm just tickled pink.
Any advice?
Be nice. And tell your therapist to be nice, or at least, professional. It's entirely possible that your mom has undiagnosed bipolar - there is a strong hereditary component, and some of her behaviors that you've described in the past suggest it.
