sorry to hear you missed out on the 2.1 by such a small margin - but hey all the best people get 2.2s!
In practice, unless you want to do postgrad study it's very unlikely that it will ever make a difference to your future options, and at least you can say that you had fun at uni rather than spending all of your time with your head stuck in a book!
now get out there and have a few beers tonight!
