There is no set time for when it happens, but sooner or later certain Danish traits are bound to rub off on even the heartiest of foreign residents.
From what you eat and how you speak to where you shop, living in Denmark for an extended time can change you.
1. You mix Danish into your mother tongue
When you drop 'altså' into the middle of an English sentence for the first time, the signs are there.
You might then begin answering ‘Jo, jo' in the affirmative to one of your non-Danish friends' questions, or start doing that weird sucking-in-air-while-saying-ja thing that the Danes do. By the time you start saying 'Tak for mad' to your mother when she cooks you a homecoming dinner, you'll probably have been in Denmark too long.

2. When you go back home, you're annoyed that you have to drive
After living in Denmark with its vaunted cycling culture and expansive public transport networks, it's easy to forget that getting around in other places isn't always as easy. This is particularly hard on Americans who on trips home have to trade in the freedom of their iron horse for the steel prison of the automobile.

3. You do multi-stop shopping
Do you do the bulk of your shopping at Netto but then swing by Irma for some organic goods, Kvickly for the beer selection, the local butcher for a choice cut of meat, and then Føtex for the American peanut butter you can't find anywhere else? Congratulations, you shop like a Dane. Bonus points if you scour all the circulars and plan your shopping route by what's on special offer this week.

4. You scoff at bottle openers
Now that you've purchased those various beers, you need a bottle opener, right? Pssh, not if you're like a Dane. Lighters, another bottle of beer, tabletops, even teeth are amongst the many instruments used to pop open your beer ‘Danish style'. A true litmus test amongst expats.

5. You stop jaywalking
Many an expat has ridiculed the Danes for their habit of waiting for a green light to cross the street, even when there is not a vehicle in sight. If you find yourself doing this too, you may have been in Denmark too long.

6. You adopt Danish pride
OK, you probably won't root for them if they face your home country, but gradually you will find yourself proudly cheering on the Danes in international competitions like the Olympics, Women's Euros or Eurovision Song Contest. When back home or in a third country, this feeling of Danish belonging becomes even more prominent.

7. You forget about the after-work drink
Back home, you wouldn't have thought twice about offering or accepting a spontaneous offer to grab a drink after work. But after extended time working with Danes, you'll know that they're more inclined to head straight home when the working day ends (which is usually quite early). After a while, you will stop asking and then the day will come when you are shocked – shocked, I say! – when someone dares to invite you for a spur-of-the-moment drink.

8. You join the rugbrød cult
Danes love rugbrød, the hearty rye bread that is a staple in lunch packs and the basis for the famous open-faced sandwiches, smørrebrød. Resistance is futile and eventually you too will opt for rugbrød. You'll find yourself topping it with potato salad or paté and beetroots. And when you go back home home, you'll suffer a case of rye bread withdrawal.

9. You turn off the subtitles
Television is a helpful tool for learning a new language. Upon arrival in Denmark, most newcomers are unlikely to make any sense out of what they are hearing, but after some time – and language courses – things start to make sense.
Before you know it, you'll be enjoying Denmark's world-famous shows in their native language with the help of Danish subtitles, and will eventually be able to turn off the texts altogether. At that point, why not try going next level: watch The Bridge and try to understand what on earth the Swedish characters are saying.

10. You feel affection for the royal family
Did you shed a tear when Prince Henrik passed away earlier this year? Consider the Queen's New Year speech an essential annual tradition? Won't hear a bad word about Crown Princess Mary -- and not just because, like you, she's a foreigner?
Denmark's diverse foreign residents hail from both republics and other consitutional monarchies like Denmark. But if there's one thing most can agree on, it's the agreeable Danish royals.
