I am on Facebook often. Social media is part and parcel of being an author (The Travelers, Saguaro Books). You have to stay connected. Some parts of social media I enjoy more than others. Honestly, I find the Facebook part mostly taxing. So what does this have to do with metaphors? It's kind of a strange leap. But here it goes...
Almost everyone, at least in the US, watches TV daily. We consume shows and movies like they're candy that our parents might suddenly take away. We all have our favorite genres and actors.
Prior to taking the plunge into the world of being a published author, I was unfamiliar with many things - the publishing industry in general, book marketing, social media, etc. Now things are different. I've started to understand the social in the social media. It's also opened up my creative side, beyond writing, in that I've become a wee bit obsessed with bookstagrams.
I grew up in a government family, so acronyms became words whose meanings I rarely understood. Some of them I even thought were just words being used wrong. My family would say something that sounded like "scissor" in a sentence where the word "scissor" had no place! I realize now it's some sort of acronym, I still don't know what it means though.
