That's OK just phone me about 1 hour or 45mins before you think that you will finish and I'll drive over to collect you. I will send you my home (best to ring me on one of those) and mobile numbers in a DM tweet on twitter.

I don't know what you want to do no saturday, but if you want to stay some extra time you are welcome to, and if you need taking back to cambridge, Peterborough or Huntingdon stations I can take you there the next morning.
