Believe, me, I don't like "piffle" as a response, either! But you could have just let it go.
I don't "let" things do. I am not conditioned by the feeling types like social workers, therapists, and in businesses and industries where women predominately work, for example, hospitals and public school systems. I act on transgressions because I am the man that women marry and vote for because they know when a burglar enters I will fight to the death if necessary to defend them.
