I never noticed it before yesterday, but this city loves their hand shake. Walking from my home to the end of the street is like running a gauntlet. It's an active traffic street, but still very pedestrian with shop keepers and employees on the sidewalk talking and smoking. I know most of them and as I approach they will stand if seated and take steps towards me to greet and shake my hand. They do it among themselves as much. More than what my impression of Texas is, and we do it a lot in Texas. When I reached my destination in Buda, a sweet wine bar, more of the same. I remember in Istanbul and Albania the hand shake seemed a but unexpected and foreign to the locals, but its a habbit I have.
Hugs. In the south we hug everyone, even "almost" strangers. (EDIT: but its become a lot less common except in te country) Try that here, I have out of habit, and they are shocked. I remind them I am from Texas and usually get a laugh. Not always.
The double cheek kiss here is less common than 20 years ago but still see between close friends and the older generation on ocassion, but not often.
Your observances? This is just for fun.
