- Say hello, wave goodbye
Entering a shop or arriving at a cash desk it's polite to offer a cheery greeting to staff. And as you leave say thank you and 'good day'/'good evening' (in French using the specific terms bonne journée/bon soirée).
- Giving gifts
When visiting someone's home it's appropriate to bring wine, flowers or chocolates – choose the brand carefully!
- The wrong language
In Flanders don't think it's clever to speak French. English will generally be better understood and better appreciated.
- Liberal or conservative?
Local ideas about political correctness might not match your own. Don't jump too quickly to conclusions. A lighter hearted approach to serious issues is common, and underneath, many attitudes are very liberal.
Traditionally Belgians welcome good friends with three kisses on alternating cheeks. But knowing when that's appropriate confuses even the locals.
