He said, she said.

She:  "Honey, for Christmas I want one of those A to Z Guides of London.  All the blogs say you have to have one if you're gonna live in London."

He:  "Yes, dahling.  But, it's pronounced A to Zed, not A to Z."

She:  "No it's not."

He:  "Yes, it is.  X... Y... Zed."

She:  "But, that's not even a letter.  It's a word." 

He:  "It's a letter.  Zed."

She:  "But you have to spell it.  Z... E...D."

He:  "It's Zed."

She:  "Whatever."

He:  "Would you like a cuppa tea, dahling?"

She:  "No."

He:  "You know they won't let you in if you keep this up."
