One thing I never planned for in adulthood is developing a strong preference for trailing punctuation to remain outside of quotation marks¹ unless the period, comma, or other punctuation mark itself is being quoted. I wonder if the people I work with, who read my emails and technical writing every day, think I don’t know how quotations marks are supposed to work in American English². No one has ever called me out on it. Either they don’t know that trailing punctuation is supposed to go inside quotation marks in most cases, they don’t care about it, or they don’t notice it at all.
