Using “that” and “this” interchangeably
What is the difference?
- What do you think about that?
- What do you think about this?
What is the grammar rule about using this and that in this way?
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Where relative spatial proximity is not present, we could then depend on emotional-proximity.
Being relatively detached
Being relatively more affected
