You believe god made you special, so special you need to control this board for the good of everyone. Sounds like jew think to me.
It doesn't have to. I used to transcribe for work and looked this up in my quest to have perfect punctuation. The reason I eventually came to was it is a slight cultural difference and Americans think the period within the quotation marks looks cleaner. Just like how we spell words differently for no reason.
