The thing is, Europe is has a lot of countries. Except for the Eastern part, where Russia covers 1/3 of the continent. Geographically it would make sense to consider Romania as a part of Central Europe, however culturally or geopolitically few Romanians would disagree that Romania is part of Eastern Europe. Even our manuals say that Romania is part of South-Eastern Europe ;)
Ah and in my circles Russia, despite maybe even publicly being considered European (is it?) is considered Asian. There even the political distinctions are completely ignored it seems.
This "central Europe" thing is very funny indeed. I've lived in the Netherlands - they think of themselves as "Western Europe". In the UK everyone knows Europe is split into West and East by the Iron curtain.
For me as a Czech, Eastern Europe is everything East of Slovakia - Ukraine, Romania, Belarus. But try asking a Romanian - they'll tell you Romania is Central Europe! When you ask them what is Eastern Europe then, you'll learn it's Ukraine and Russia.
