School?
The majority of Kaleido Stage's performers are kids. Sora is what, 16? (Layla and Yuri are maybe 20-21, but they're just about the oldest performers there) And they all devote all their time to the stage, whether it's the actual performances (a morning show and an evening show, and possibly an afternoon show too!) or practicing. So when on earth do they go to school??
It makes no sense. Performing at Kaleido Stage probably brings in good money, but only as long as you're young and fit. I doubt there are many performers over 30 (in real life I mean) so once you're past that age you'll need an education. And these kids don't have anything later than, I dunno, Junior High?
Meh. Just my thoughts on the subject ^^;;
