So we would normally have made up our prom in autumn. because of corona we couldn't do it at the beginning of the year. There was also a dance course especially for the prom, but I wasn't on the dance course because I couldn't afford it at the time and because I generally didn't feel like doing it because I don't like to dance. and the teachers also said that those who werent in the dance course could also go to the prom. But now the teachers suddenly say that those who weren't at the dance class are not allowed to go to the prom. is that fair or unfair?
