I agree with both Winston & MFillingham that it good for you to stop and be applauded. I also think you were were brave to do what you have done with the number of dickheads around today who think twice about giving you a ood hiding. So yes in my books you need a bravery award. As for the police response, it just shows their lack of emphathy these days.
As for the poor lady getting help, goodluck with that! Ive been trying to get help for my Autisic daughter angry, often physical meltdowns since she was born. Yet there’s all the help you can get for her physical disability!
