Friends of ours. We tend to spend a lot of time with these two — because they’re people around whom you can just be comfortable, talk crap, enthuse about Radio 4 programmes, drink beer (or Pimms), have a barbecue, laugh about Flight of the Conchords, play the guitar badly, eat vege breakfasts, discuss university life, and debate the pros and cons of various singer/songwriters.

They feel strongly about the kinds of things we feel strongly about, but tend to actually do things about it. Always saving the world.
