Kyon's Sister humming Hare Hare Yukai

Episode 6 around the 6:30 mark.
I find it amazingly adorable how she just barges in the room while humming and grabs the scissors for her class. I wonder when we'll learn about their names.
If you're looking for Haruhi related songs I made a playlist:
• Kyon; Hare Hare Yukai ...

I think everyone who watched the show would like to know the name of both Kyon and his sister. But sadly, we probably won't know it.

It's a nice mystery though.

Actually have been listening to different versions of this song for almost the entire week now.
