The “part of the world” you are talking about, is southeastern Europe.

There is a problem in your theory.Greece doesn’t even fully belong in that part of the world.The same goes for Turks, from a different aspect.

Turks are an Islamic nation, with strong influence from Mediterranean and Balkanic nations.

Greeks are a mediterranean nation, with many similarities with southeastern Europeans, mostly with Bulgarians, Montenegrins and Serbs.

Southeastern Europeans are Slavic.

BTW, when someone is “getting on our nervs”, it’s because either he reminds us a bad aspect of ourselves, or because he there is an aspect of him that we would like to have.For example if I like a girl and see her with someone else, this one will possibly make him to get on my nervs.
