Context: It was particularly unsettling because otherwise he seems totally chill and calm and collected and not violently repressed . I had a doctor 's appointment today that was , for the first time , not with a pediatrician . It was weird mainly because in the past , I always felt that the doctors were cool but sort of talking down to me . But today my doctor was a 30-ish lady doctor and I felt like she was treating me more like a peer than a kid . So that was nice . I was off work again today .
