You start off with your once a week session in the local hall for £3, but as soon as you hit puberty it’s like “you need to pay for 4 hours of lessons a day 6 days a week, 10 pairs of ballet shoes which last about 10 minutes and a load of costumes for shows and if you don’t want to do that, you’re out”. So a lot of people, like me, quit. Both because their parents can’t/won’t pay for it, and because they don’t want to devote every waking minute to ballet.
