my guess,
north-west (Thrace) is in europe, south-east is in middle east, and the rest is in asia. geographically!
but if we make a mental classification!
thrace, west anatolia and south anatolia is in europe, east anatolia is in middle east, and north anatolia and center anatolia is in asia!
As a north Anatolian I liked to think I was European in the past. But now I am not sure. I am realising that I have strong ties with middle east too. I am really in between. And this causes an identity crisis for me.
