While and Whilst I consider myself a pretty good writer. I think that my punctuation can be great and that my grammar is also great, and to the point where I get annoyed when I read something - mostly fanfiction - and the grammar or formatting is off. It just ruins the entire fiction for me, and no matter how good or interesting the content is, I am just not able to read on further. But I am not perfect and still have a ways to go as far as my writing is concerned, which is why I want to ask: when do I use while over whilst, and when do I use whilst over while? I always seem to get the two mixed up, or I will just use whilst, because to my ears that sounds like the safest one in the context of the sentence that I am writing or typing out.
