The first Monday in February Bernadette's research group had their weekly meeting. All 5 of Bernadette's Ph.D students, postdoc Dr. Andrea Gonzalez and experimental officer Dr. Jane Parker were there.

Bernadette: "Hello everyone, thanks for coming. OK, I will start with the big news. The rumours that you have been hearing are true. Sheldon and I will be away from Caltech for six months from April, we are off to Cambridge University for a visit. My visit is a follow on to the collaboration we had last year with Ellen Rashid. Sheldon has lots of friends in the Physics department in Cambridge from his collaboration with Stephen Hawking. Everything was finally confirmed this morning."

Andrea: "So who will run the group in your absence Bernadette?"

Bernadette: "That's why Jane is here, she will help you with the day to day organising of things but you will run the group in my absence Andrea. I will keep in touch the best I can by Skype and email from Cambridge, we are 8 hours behind in California so you might hear from me early in the morning. I will definitely have to Skype when we interview for new Ph.D students to start in October, I would like Andrea and Jane to do as much as possible at this end to arrange the interviews. We will have a lot to do over the next 2 months, any big equipment orders should be sorted out by the end of this month. Sanjay and Francesca have both got their Ph.D thesis defences later this month so we all need to help them get ready. Luther, Sally and Jennifer should pay attention to all this as they will hopefully be doing this next year. All my teaching should be finished by the middle of March."

Jane: "Don't worry Andrea, I will give you a hand. This is all practice for when you get your own Ph.D students in a few years time."

Bernadette: "OK, next item on the agenda. Francesca and Sanjay, is everything ready for your thesis defences? Do either of you want to have another practice examination before the big day..."

The next Saturday the whole social group were at Sheldon and Bernadette's house. Josh and Debbie and Marie were playing with the cats whilst their parents, aunts and uncles were discussing the Cambridge trip.

Leonard: "So everything is confirmed then, you will be away for six months."

Sheldon: "That's right. We leave on March 31st and return on October 1st, direct flights between LAX and London Heathrow. Someone from the University will meet us at the airport."

Penny: "So what will happen with your house?"

Bernadette: "Caltech will rent it out for visiting scholars in our absence."

Suddenly they could hear Marie shouting out "Kitty Cats!"

Leonard: "So what about Einstein and Hawking. We could look after them for you. Marie has been asking for her own kitty cat, she really loves your cats."

Sheldon: "That's very kind of you Leonard, is this OK with you Penny?"

Penny: "Sure thing Moonpie, I think we can handle 2 cats. Just don't get 25 cats before you leave..."
