Hall social is good preparation for Fresher's Ball, obligatory drunken night with thousands of other freshers, a few third year letches (you'll start to recognise them), and terrible 80's throwback (we had Chesney Hawks). A good idea is to get your parents to pay for the tickets before they go, in a specially crafted, 'I'd like to go, but I'm going to have to be careful with my money' kind of way, that becomes fairly tired by the end of the second year.
