Congratulations!
Whether you’ve decided to adopt a Brit, befriend one, or like me, marry and have children with one, I’m confident you’ll benefit immeasurably by the addition.
Having a Brit in your life will enrich it. You’ll learn new words like twee and new uses for old words like fanny. You’ll enjoy hours of endless debate over the edibility of Marmite, and shake your head in wonder at why the Brit in your life can’t just call a line a line and leave Q to rest peacefully between P and R where it belongs. Scrabble is especially fun, like when your husband spells tyre in accepted British English on a triple with a ‘y’.
Jokes aside, you’ll find that proper care and maintenance of your Brits will go much more smoothly if you get used to a few things first.
Bunting
Oh my, do the Brits love bunting, those fabric triangles waving in the Atlantic breeze. A British friend recently asked me how Americans refer to bunting and was gobsmacked when I told her we don’t. Bunting in the US is something that happens in baseball. But in order to keep your 
Brit happy you must utilize bunting for every occasion deemed out of the ordinary: birthdays, anniversaries, celebrations, royal weddings, and sunny days. Bunting can also be found strung from corner to cornice in twee British villages with names like Mother’s Fat Bottom and Speckled Dick.
Tip: To keep your Brit happy, keep emergency bunting at the ready and whip it out when called for. To avoid disappointment, always err on the side of bunting.
G&Ts
In NYC, G&T refers to ‘gifted and talented’, aka, the program you hope your pre-schooler tests into so you don’t have to shell out 40K a year for private school. But not so in the land of Hope and Glory. Gin and tonic is practically a national pastime in Blighty. A g&t will be 
appreciated by your Brit at any time of day. After all, it’s five o’clock somewhere in the old empire.
Tip: Don’t confuse g&ts with Pimms, a summer drink made with lemonade (that’s not really lemonade, but Sprite) which will sneak up on you and knock you flat if you’re not careful.
Cuppas, Cossies, and Hols.
Your Brit will feel more at home if you adopt the habit of shortening all your nouns to adverbial sounding nicknames. Football is footy. Cookie is biccy. A bathing suit is a cossie and a television a telly. Umbrella is brolly and when you don’t need one and want to relax in the sun you can chuck a sickie from work. Barry is Bazza, Sharon is Shazza, and Gary is Gazza. Vacations are hols, Bob’s your uncle, Fanny’s your aunt.
Tip: To your Brit, fanny’s a front bottom, not a bum and a bum is not a bum either, but, by process of elimination, a back bottom.
Put the Kettle On
If gin and tonics start at five, every beverage before is tea. There are approximately 500 different types of tea. Lipton is not one of them. There is a right way to make tea and a wrong 
way to make tea. But…pay attention because tea also refers to dinner, which for your Brit means lunch, which comes slightly after elevenses which seems to nestle between breaky and tea. More than just tea drinking, however, the ritual act of putting the kettle on is a metaphor for community, conversation and problem solving. If Americans stop to smell the roses, Brits put the kettle on.
Tip: Unless you want to send your Brit into fits of unhappiness and risk permanent displeasure, do not microwave tea. Builder’s tea is regular tea with sugar. I do not know why it is not Plumber’s tea or Electrician’s tea except that it is not.
Taking the Piss
Note: this does not mean emptying your bladder. Taking the piss is entirely different from taking a piss. The art of taking the piss, or banter for the posh folks out there, is the British knife-edge between gentle mocking and downright nastiness. Perhaps not surprisingly, most non Brits find the habit peculiar and off-putting, especially as the art is honed on family and friends. There is a complicated value system based upon how much piss one can give and/or take, and after twenty years, I am none the wiser as to how it works.
Tip: None. A twenty year learning curve and nothing.
There you go. If you properly care and maintain your Brits, I’m confident you too will enjoy decades of bunting filled joy!
Now, keep calm and put the kettle on. Unless it’s after five, in which case, crack open the gin.
