Very roughly, the Europeans north of the Alps are more reserved than those south of them. A Swede is more reserved than a German though, but an Englishman can be just as reserved as a Swede.
The extrovert, chatty Europeans are the Italians, Portugese, Spaniards, Greeks and Yugoslavs and to some extent the French. Once again, roughly speaking.
