The rest of the social group had been travelling over the Xmas holidays, Sheldon and Bernadette didn't get to see their friends until New Years Day. This chapter starts as Sheldon opens the door of their house.

Sheldon: "Well it's Professor Hofstadter and his family, Happy New Year to you."

Leonard shook Sheldon's hand and said "Happy New Year to you Professor Cooper."

Penny gave him a hug and said "Happy New Year Moonpie. What do you say to Uncle Sheldon Marie?"

Leonard and Penny's daughter said "Kitty Cats!"

Sheldon: "Yes Marie, you can play with the cats. Josh and Debbie are already playing with them."

Bernadette: "Happy New Year Hofstadters, welcome to our humble home. What would you like to drink? Make yourself comfortable."

Five minutes later.

Sheldon: "Now that everyone is here we have some news."

Amy: "Are you pregnant Bernie?"

Bernadette: "No Amy, just cats in this house, no children. Over the last year at Caltech we had a visiting Ph.D student from Cambridge University in England, she went back to England just before Xmas. My old boss Professor Kariuki was a Cambridge student and he has arranged this collaboration. Just before Xmas he told me that Cambridge would like to invite me over for a visit for six months starting in April."

Raj: "Wow, that's great news, I wish someone would arrange something like that for me. I would love to go back to Cambridge."

Howard: "So what happens to you Sheldon, will you go with her?"

Sheldon: "I hope so, Bernadette's trip hasn't been confirmed yet but I have emailed some of my friends in Cambridge Physics telling them of Bernadette's proposed visit. Hopefully they can have me as a guest at the same time. It's a shame that Professor Hawking isn't with us any more, it would have been great to have collaborated with him again."

Bernadette: "We will know more when we go back to work tomorrow. We had a good time at the conference there a few years ago."

Howard: "We had a wonderful time there on our honeymoon."

Amy: "Yes we did, you get to spend six months there, lucky you."

Suddenly Stephen Hawking and Albert Einstein came running through the room followed by Josh and Debbie Wolowitz and Marie Hofstadter. Marie was shouting "Kitty Cats!" at the top of her voice.

Sheldon: "Looks like the children and cats are having fun."
