Today, particularly in the West, we live in a very complex, divided & disordered world.
For example, I recall when I lived in Thailand, how polite the social norms were in regards to speech. Its funny, recently, each morning, I see an older Thai lady who has moved to where I live (in Australia). Each morning we cross paths when doing our morning walks and we have a light chit-chat Thai style. It is so polite. It is so different to the Western world.
Also, where I live, we currently have an influx of young Spanish backpacker workers. For some reason, suddenly there a many young Spanish everywhere. it is noticeable their cultural norms & speech are fairly abrupt.
My impression is Buddhist monks & nuns, as well as advanced Buddhist practitioners, generally limit their social interactions & social environments. This helps them control their speech.
Once speech is under control, a Buddhist practitioner examines & accepts the harsh realities of the world around them, to subdue anger. Buddhist practice is to give up longing (desire) & disappointment towards the world. This is what the Buddha taught in his definition of mindfulness.
