"I knew having that double wedding with you and Anthea was a TERRIBLE idea," Sherlock groused as he looked out the window of the private plane they'd rented for their shopping trip. "Look at this list my wife gave me!"
Mycroft rolled his eyes and consulted his own list. "How was I to know we'd cause my wife and Molly to infanticipate simultaneously? Anyway, we are to go to Yverdon-les-Bains for bouchons vaudois next. Who knew your wife from Nowhere, Northhamptonshire had such a selective palate? It's a good thing MY WIFE has much simpler tastes."
"Pack it in! It's not like we're going there just for MY WIFE! Anthea wants boutefas from there, too!" Sherlock retorted.
Behind the two brothers, John sat with an amused smile on his face and a list of his own in his hand because Mary was expecting again. "Oh, come off it. You two berks just like saying MY WIFE all the time, honestly."
"SHUT UP!" the Holmes brothers both shouted at the doctor.
