Well just that, really. Assuming that a student is sociable enough to have friends at different colleges, it is nice to be able to think of going to a number of different balls, especially in the summer. Except that the 'cheap' ball tickets are £85 and more usually £120. A young student recently won free tickets to two balls, totalling £210. Given that the balls are the main college social events this is sad. Min budget for tickets to go to, say, 5 balls a year including the Union ball but excluding a law society ball would be £700. The rich, in short, only dance with the rich.
