Gestures and greetings
Luxembourgers are somewhat reserved and formal, but once you start interacting with them, you'll start to feel more at ease. In Luxembourg Culture, A quick handshake is the most typical greeting. The cheeks of two very close friends are kissed three times. Women and men kiss each other more frequently. Typically, hardly much touching occurs when having a discussion. Hugs and handshakes, on the other hand, are welcome gestures that convey friendliness and empathy.
A slight nod or eye contact is preferable to pointing someone out with your finger. Hand gestures aren't used very often in general. It is better to use more subtle body language, such as little nods and attentive facial expressions. Use surnames with the honorific titles Monsieur or Madame in the majority of social settings. It is preferable to use the formal pronoun for you, "vous," rather than the informal "tu," when speaking in formal circumstances. Unless they want it, avoid using someone's first name.
