People react to them in different ways. One way is to snap, tell what comes first to your mind, and brush aside those people and situations brusquely.
The other way is not to react, either by words or action, immediately. Wait for tempers to cool, and sort things out. Also, react in such a way that a situation doesn't get worse; instead engage in such a way that a resolution can be brought about.
My experiences in life have taught me that it works better for me when I am cautious and prudent rather than abrupt and impulsive. Probably it works the other way round for some people.
Diplomacy gives the room to adapt to situations, which means one gets more opportunities and avenues. It opens up the situations for one to look at different ways of moving forward.
Being diplomatic doesn't mean always being nice, flexible and accommodative. That could spell disaster. Sometimes being firm and abrupt can be a part of being diplomatic; because such an approach would be essential to yield a solution.
Diplomacy is sometimes misunderstood as surrender. One way I look at diplomacy is: the art of taking one step back in order to move two steps forward.
I will leave you with two quotes:
"Diplomacy is the art of telling people to go to hell in such a way that they ask for directions."
― Winston S. Churchill
"Tact is the knack of making a point without making an enemy."
― Isaac Newton
