I have a several very good friends who speak very loudly in public. I am also, to some people, a very good friend who speaks very loudly in public. Both these facts occasionally lend themselves to some awkward situations. I have been on several modes of public transportation with a friend who is screaming about her latest sexual conquest, and I have had to ask her to pipe down for the sake of the mothers shielding their children from us.
I have also been that friend, and I appreciate how embarrassing it is to be shushed in the midst of your passionate defence of The Last Jedi.
