Puzzle 4 - Ryuuko & Ushiko

(The door to Ryuuko and Ushiko's room is open. Mimi peeks in.)

Hello, is anyone here?

Ah, Mimi, hello. Sorry, guess I forgot to close the door.

Come in. Did you need anything?

No, I just, uh... I was just walking by. No reason.

So you came here to hang out? That's unusual.

I'm happy, though.

So, umm... what is Ushiko-san doing? She hasn't even noticed I'm here.

Oh, I think she's planning her weekend work shifts. Oi, Shii, we have a visitor!

Hmm? Oh!

I'm so terribly sorry! Got a bit too absorbed in this.

Planning shifts, huh? Can we help you somehow?

Well, you see...

This weekend, I wanted to visit my parents, and do two shifts at work. One of the two needs to be a night shift.

I also want to catch up on some chores. To be precise, cleaning up, doing laundry, and I need to do a small shopping trip, too.

I promised I'd go home on Saturday. Going shopping on the same day would be too much traveling, so I'd rather not do that.

On Friday, it's supposed to rain, and I think doing an inside chore would be a good idea. So it's either cleaning up or doing laundry.

Oh and also, I don't want to do a night shift on Friday, if possible.

And I think doing laundry would make the most sense on the day of my afternoon shift?
