I am searching for a guide or training on improving on shit test. What I do currently is ignoring the shit test and continuing on what a did before. In some cases of drama I tell the girls to leave and only get back when calmed down. My strategy works in some cases but I feel that there is a lot of space for improvement. I think sometimes being funny could be better but unfortunately currently I am not funny at all. I've read about approving and then exaggerating. Are there other similar tricks?

Can you recommend my a book or blog on this topic?
