In some cultures, you signal respecting someone's time by not bothering them.
replyIn other cultures, you signal respecting someone's time by making small-talk with them.
Advice about making small talk vs. not making small talk is not really useful unless it acknowledges this cultural divide and the percentage chance a stranger falls into one culture or another.
This was also my observation after growing up in New England and then moving to Denver, Colorado. People were much more open to conversation than I was previously used to which felt like a breath of fresh air. I realized people in New England seemingly default to a “defensive” interaction mode when conversed with without a pre-shared common ground, such as a task or moment. Its quite apparent when visiting family back east.
replyFellow New England -> Colorado transplant. It was pleasantly shocking for me too how much chattier and friendlier people are in Colorado. But now I've lived in Colorado long enough that when I go back to visit New England, it's shocking how cold and taciturn people are there. Conversations with strangers rarely get past "How ya doin?" "Fine and you? "Fine, thanks."
replyI do appreciate how direct people in the northeast tend to be, and sometimes miss that aspect of the culture.
