i know very little of other languages' grammar rules and so i would love to SEE (feel) kindness to our members who are learning English and want to join in on something like this but feel apprehensive.
This will be nothing less than kind. Punctuation ( as grammar ) varies in different countries. I have only been instructed in Western ( America & Canada ), and British ( England, Australia & New Zealand ). While most of the styles have merged, there still remains some differences regarding how quotation marks are used as well as periods within/out quotations and titles. Listing time and dates also differs slightly. My own writing tends to utilize both, depending on what my personal preference is.
For example, I prefer to use regular quotation marks for quotes, and apostrophes for quotes within quotes. This is the Western method, where the British is opposite, placing apostrophes on the outside quote while using quotation marks on the inside quote. Conversely, I prefer to place my periods outside of quotations, which is the British method, vs. the Western practice of including them inside the quotation.
It all comes down to personal preference and what you feel comfortable with. Either use is proper, imho, except, for perhaps, turning in homework such as a thesis in a respective country who requires their own punctuation.
