I couldn't describe the Belgians as a beautiful people. They are shorter than the average English person and thickset. Faces are broad and square; noses are bulbous and quite large. When you see them walking around the streets, their faces tend to look quite expressionless or sullen. You'll recognise hundreds of them in Brueghel's paintings. Moustaches are more common than in Britain, and goatees too. Blond colouring is unusual.
The Belgians share the British lack of style and flare for dressing. Glasses seem to be common and have quite a distinctive style - more French than German or British, but unflattering nonetheless. Business men, if they wear a jacket at all, wear one which does not pair with their trousers, and have a soft leather briefcase tucked under their arm. Youth culture and fashions are much as in Britain - I don't remember that from before.
Most Belgians are quiet traditionalists. They support the monarchy. They are nominal Catholics. They are fairly easy-going, not easily roused to great passion. In the evenings many Belgians just go home and watch television. Smoking and beer-drinking are also very much part of the traditional male culture.
Many Belgians are comfortably off - hard-working business people. They are not adventurous - you rarely meet them travelling far from home. A saying perhaps sums up the attitude - "Oost west, thuis best" (East or west, home is best).
The Walloons don't like the Flemish and the Flemish don't like the Walloons. In the same way that the English say the Scots are tight, the Belgians say the Dutch are: The Dutch pass round a tin of biscuits and then put the lid back on.
