No problem, mate. I find myself rambling when I talk about something I like the same. Don't worry, Renpy isn't the make-all of visual novels. You use what you're comfortable with. I usually only code in C# in Unity but I like the simplicity of Python.
Moreover, other than just making a label and say "do this", Renpy is kinda my life when it comes to making and modding visual novels. It's good but there are multiple engines just as good or even better so never think you have yo be limited.
