NB: Although I use US American English as much as I can, in International English here in Europe, "dialog" and "monolog" are not used at all, which seems to mean that, for the context of International English, at least in Europe, the prevailing word this time is the British one. I will go into this one day. In any case, the standard spelling I should be using should be "dialog" and "monolog".
