Stumbled onto my own old thread Totally forgot about it.

We just got back from the Caucusus a week ago. Azerbaijan, Georgia, Armenia. We've found the locals very friendly in all places, as is generally the case anywhere in the world we go (with some notable exceptions).
We did befriend a number of local people and found them to be as warm and hospitable as we expected.

But here is an interesting addition.
As we were checking into our AirBnB in Tbilisi, the host immediately recognized we were from the US - even though we speak fluent Russian (born in USSR, moved to US as teenagers 35 yrs ago). This was literally within seconds of meeting us. We asked what gave it away - he said that after hosting for so many years, it was easy. It was our body language, apparently. He said Westerners are much more open, give off much more positive vibes, whereas his Russian, Ukrainian, and Georgian guests are much more tight, more suspicious, and far less friendly.
Just repeating what I was told by someone who deals with people from all over the world on a daily basis
