By the middle of September Bernadette was working very hard in the laboratory to get things finished off. Sheldon was waiting for her back at the Wolfson apartment.

Bernadette: "Sorry I am back so late, I was helping one of the students with his experimental work."

Sheldon: "Well done for helping but don't work too hard. We only have a couple of weeks left here, it is going to be very hectic for us preparing to leave and also when we get back home. Your research group will have plenty of work waiting for you when you return."

Bernadette: "That's true."

Sheldon: "Who knows when we will next get a chance to spend some time in England. Tomorrow is Friday, let's have a day off and go to London for the day."

Bernadette: "Let's go on the train."

Sheldon: "Now you are talking!"

Early next morning Sheldon and Bernadette went to Cambridge station and took the train to London Kings Cross station. When they arrived they had their photo taken at Platform 9 3/4 :-) They spent the morning seeing the sights, after lunch they went to the London Science Museum and they both had a good laugh correcting the many scientific errors. Then they went on a boat ride along the Thames before dinner. Finally Sheldon and Bernadette took the last train back to Cambridge after a long and very enjoyable day.

On their return to Wolfson College they both slept very well. Saturday was spent doing as little as possible and Sunday they had a fun day just walking round Cambridge playing tourist as if they weren't living there. Monday morning they both returned to their scientific work at the university having thoroughly enjoyed their long weekend.

September 30th, Sheldon and Bernadette had a farewell meal at their favourite Thai restaurant for their scientific friends who had worked with them over their time in Cambridge. They both gave farewell speeches.

Bernadette: "Thank you to everyone who has been so kind to us for our time in Cambridge. We are very grateful for the opportunity to have done some science here at this fantastic university. Hopefully the Caltech-Cambridge biological science collaboration can continue in the future. Yesterday I was Skyping with my old boss Professor Tom Kariuki, a Cambridge graduate, about possibly having another Cambridge graduate student at Caltech next year. May the collaboration between our two great universities continue for many year."

Sheldon: "Thank you for welcoming us to Cambridge, it has been so good to have been able to collaborate with the colleagues of my old friend Professor Hawking. Hopefully we can make a more formal Caltech-Cambridge Physics collaboration after this. I have a meeting scheduled with the head of the Caltech Physics department next week. I hope it isn't too long before we can both come to the University of Cambridge again."

When they got back to their apartment for their last night Sheldon got a text from Leonard "see you at the airport tomorrow."
