If you recommended them to me, it's probably best if we get to know one another better before suggesting books, films, and television shows to each other, in the interest of being mutually courteous and not wasting the other person's time.
I know y'all had good intentions. I get that you enjoyed them. I'm just not clear on why you thought I would enjoy them.
