Quickie Letter Swap: What's your obsession?

I tend to go in cycles of obsessing over something for a while (like knitting, or writing, or music), and then moving on to something else.

In this quickie letter-writing swap, you'll write a letter to your partner talking about the latest "thing" you're into, whether it's a craft, a new medium, a TV show/fandom, a book, politics, or a meme or fad. Whatever your latest craze is, tell us about it!
