There are some norms in the United States that are not-so-normal in Europe and vice versa. What should we keep in mind when flying across the Atlantic? Here are some things to note:

1. Europeans do not smile often

They're not cranky people, they just think that smiles should be earned, not freely given. Some think that constant smiling at people walking by is not genuine. So, don't assume that Europeans have bad days every day, it's just natural that they typically have a blank stare.

2. Public transportation is very common

Cars exist, but certainly are not the popular way to travel around European countries - especially in the cities. The cheapest and best way to travel when abroad is usually by tram or subway. Trust me, they're not as intimidating as they look. And even if you do get lost, you're in a foreign country. You don't really know where you are anyway!

3. The drinking age is 18

Wait until 21 no more! The drinking age is a few years younger, so you can enjoy any type of drink at 18 or above. No need to worry about being rejected from the bar!

4. The outlets are completely different shapes

Do not forget to bring your outlet converters! European countries have different prongs on their outlets than in America, so make sure to stop at Best Buy or in the airport to grab one or two before reaching your destination.

5. Vegetarians: be aware

The countries are recognizing different meal wants and needs, but many Europeans thrive off proteins which mostly come from meats. This could be anywhere from pork to chicken, veal to duck or rabbit to turkey.

Europe is an incredible continent with so many sites and spots to see. Just be aware that European culture can differ from American culture in many ways!
