You know when you have an extremely noisy oldest child who is constantly singing, dancing, acting, performing, and/or talking?

And you know this oldest child, the seventh grader, has performed on the stage, multiple times—as Mary Poppins and Quinn Fabray and Dorothy Gale?

And then you have an extremely noisy youngest child, but she’s a different kind of noisy? A more, say, dictator-y type of noisy?

And this one, this youngest one, the third grader, she doesn’t really sing—at least not usually more than one line over and over and over and over and  it’s usually something by Katy Perry that by the 15th repeat of the one verse you need to tell her to do something else?

Well, you know that rare day when it’s just the two of you and she tells you that she’d love it if you could film her because she has something she wants to show you?

Well, I guess she sings too.

She calls it The Cupless Cup Trick, since cups are overrated. Of course.
