So, the question that's always been bugging me is:
What is the proper usage of "This" and "That", not when it comes to objects or things, but when it comes to concepts.
For example, there's a paragraph that goes in a way that's similar to this:
"Coconuts kill a small number of people every year, yet wars have consumed many more lives than coconuts during the long period of human existence.
That/This fact will not change anytime soon."
Another, simpler example, is:
"Who is That/This friend you're supposed to meet?"
The basic difference between That/This is that "This" refers to a thing which is nearby, and "That" to a thing which is farther away.
So, how do you use the two words when it touches such vague examples? Does it even matter? Or maybe it would have been This when the statement is inside the same paragraph, and That when it's in another?
