I'm writing an essay. I know that I can alter or add words by using square brackets. However, I'm not sure if changing a case of a single letter applies to that rule. I didn't actually use square brackets in the past, so I'm not completely sure about it.
I have this direct quote: “Sometimes that meant we kept things from you, lied to you. Yes, in many ways we fooled you.”
I'm planning to write it likes this. Miss Emily shares that “[s]ometimes that meant we kept things from you, lied to you. Yes, in many ways we fooled you.” This is without an in-text citation, for example.
Should the period be outside of the quotes or inside?
Thanks in advance.
