I have two key cards I use for work, one for opening doors, and one for clocking in.

If the door card is near the clock in card, the clock-in card will not work. The door card works regardless of whether the clock-in card is nearby.

I want to make a single card holder that will work for both cards without having to take my clock-in card out of the holder.

Is there something I can put between the two cards in the holder so I can just flip it around based on which card I need to use?

After the first chorus in The Mermaid's Song, they do this choreography where they make this shape behind Rinka and sort of shuffle across the stage. Moka and Miu are pressing their hands together above Moka's head, and Miu's other hand is behind Mona, who is holding her hands out to the side. The lyrics here are, I think, "the moon looks like it's waving its hand," which I take to mean either looking at the reflection of the moon on the surface of the water, or looking up at the moon from under the water. Their positions seem so specific that I feel like they must be making a particular shape. But what is it? A ship? A mermaid's tail? Am I looking too deep into it?
