"I don’t know how many people will agree, but striking up a conversation with an American stranger is much easier than it is with an Indian stranger." LOL, as an Indian, I relate to this so much. In India, if a stranger walks up to you, nearly 8/10 times it's either to ask you for money, directions, or to scam you. So naturally over time, you develop a thick skin to avoid strangers or keep interactions with strangers…
Same in Eastern Europe. Small talk with strangers is generally not a thing here.
