By the way, break the whisper.
I know there was no previous conversation, it doesn’t really make sense to say, but saying BTW all the time, even when it’s not super relevant, is a habit I’ve picked up from Tumblr. It’s a popular tactic to make posts sound like they’re a snippet from a larger conversation, which is common in the style. People like making posts referencing other posts without context, the “you had to be there” kind of thing, and making short posts that sort of “build a larger world” that you can imagine in your own head.
