that incident was imprinted in you, but how has it worked out for you since?
my guess: you failed to learn anything because of course that focused seminar doesn't teach anything related to the kind of mental health emergencies that occur on San Francisco streets, and so thats a decent crutch for you to lean on to not engage with them yourself, overriden by your own self preservation instincts. or are you now a mental health case worker that responds to these instead of the police? or do you know how to call those groups now so that you aren't the confused bystander like when you first moved?
