It's very strange to see you simultaneously say that that friendships take longer to develop but also that I'm supposed to avoid shallow talk the entire time even when my friendship is very shallow.

Especially since it's usually Americans that have the reputation for treating strangers overly familiar in conversation.

I don't get your point:

- Avoiding shallow talking means not wasting the other person's time - this is politeness.

- You can also talk about deep topics with people who are outside of your friendzone.
