Along with that, if they ask a question that "stumps" you, it's usually ok to come back to that one later. You may think of a good example while talking about a different scenario.
If you need a few seconds to think, repeat the question back or ask them to repeat. Good luck!
I agree, nothing ruins a PvE game more than forced PvP.
I used to play The Division, and there's a lot of other examples.
