I have been taking a lot of trains. Can't stand the "Lashon Nekiya" I hear. It is not only the vulgarity that disturbs me. It is the fact that people aren't embarrassed when others hear them speaking that way. I can only thank G-d that I was raised as a civilized human being with some sense of propriety. My Avoda is to uproot very trace of animal that is within me still.
