Some Edinburgh shows try to butter you up with a badge. Some offer free sweets. In Cerys Bradley's Not Overthinking Things 2019 I got a free autism diagnosis. Not everyone gets this - I volunteered to try to interpret a "frog book" that is used to identify autistic traits. Needless to say the results suggested I'm pretty autistic. Which is not a big surprise as before I was able to relax enough to write this review I lined up all my pens and pencils in order of length.
