Then neither does Margaret, at least on that subject.

When Saturday morning rolls around, Margaret spends way too long in front of her closet, contemplating her array of identical cargo pants and nearly identical shirts. She settles on the least worn-out pants and a green t-shirt that matches her wings, then spends another ten minutes going back and forth on having her wings out. When Bella arrives, she's wearing the wings and a nervous expression, and everything is set up for the next set of medallions.

Bella has her wings on too! And her tail. "- wow, I would never have my wings on indoors if they didn't help me balance. I guess yours're more compact?" she remarks, heading over to where she needs to do her sphinxy thing.

"They're alright if I keep them pulled in. I just really like them. It's cool that yours help you balance." She flips one of the engraved medallion disks over and over between three fingers.

"It's useful! I don't think I could actually run but I do fall over less. Right, here goes."

She sets about enchanting.

Enchant enchant enchant this is going very quickly or possibly way too slowly.

"I have something to say before you leave," she says when they're done.

"...okay?"

"I think you're really amazing and I would like to go on a date with you," she tells Bella's shoes.

Bella's shoes do not respond, but Bella says, "- oh. Well that's, uh, certainly a way to address an ancestral ethnic conflict, isn't it. I don't think I have actually claimed to be bisexual in your hearing -"

"It's totally fine if you're straight. Or just don't like me that way. I will be chill and professional and not mess up our research collaboration."

"I appreciate that but the reason I specified bisexual and not gay is that you could conceivably have accurately heard the first one. I'd like to go out sometime, do you have a variety of out in mind?"

She takes a moment to make sure she parsed that and then grins. Bella! Wants to go out! With her!!

And now she needs to come up with a date idea, which she did not already do because she did not think she was going to get this far. Movies are traditional but you can't really interact at a movie . . . "Um, a museum maybe?" 

"I like museums. Also we can teleport, so that's going to kind of delimit the selection. Let's go... to... the Louvre."

"Ooh, yes! I can get some nonmagical use out of my French. I'm free for the rest of the day, or we can pick a different day if you had plans after this."

"Today works but we will need euros first."

"I can go to the bank and get Euros and meet you back here in an hour?"

"Sure." She digs around in her pocket for American dollars to contribute to this venture.

Margaret looks up prices and accepts some American dollars. Then she can go grab enough Euros for two tickets to the Louvre, plus some extra in case they want food or something while they're there.

Bella is there when she returns!

"Hello again! I have Euros. Do you want to teleport to a ways up and catch ourselves, or would you rather I look around for somewhere we can teleport in at ground level?"

"I was imagining going invisible and finding a place to become visible and walk out."

"Oh, yeah, we'd be invisible either way, I just mean that at ground level it can take a bunch of tries to find coordinates where you aren't overlapping anything. We can see how clear the nearby sidewalks are."

"I haven't actually tried catching myself in the air. It's probably a useful exercise but maybe not for the first time in Paris."

"Yeah, it takes some practice. Let me poke around on Google Earth and find somewhere without too much traffic."

After a minute or two she reads off coordinates for a side street near the Louvre where nobody is likely to bump into them before they turn visible.

And they can turn invisible and go there!

And it turns out nobody is hanging out in this boring alley, so they can just re-visible and head to the Louvre! It is the fanciest museum Margaret has ever been in.
