France, like the United States, is an industrialized western country; however, some customs and habits differ from those in the U.S. Being aware of these differences may help your transition into the French culture.
Your neighbors expect you to take the first step to get to know them.
When invited to a person’s home for dinner, it is customary to take some wine, chocolate or flowers. Do not take chrysanthemums, as this is the flower that the French associate with death.
If someone drops by uninvited, it is not customary to invite him or her into your home. It is acceptable to stand and talk with them at the gate or door.
Always address people formally with Monsieur or Madame, and do not use first names unless asked. Likewise, when you speak French, the formal vous is preferable until you are invited to use the informal tu form.
Always greet clerks and service people on entering public places – stores, banks, gas stations, etc. – with bonjour and say au revoir when you depart.
At some time in the month of December, a bonus called étrennes de fin d’année is often given to the postman, concierge, trash collectors, and fire brigade. A donation of €5 to €10 is customary.
