Question 1

What is the difference between Irony (situational) and Coincidence?

Accepted Answer

Situational irony is an outcome that runs against what the set-up led you to expect, often as if mocking the plan: the fire station that burns down. A coincidence is two things lining up by chance in a surprising way, with no expectation reversed: meeting your neighbour on holiday abroad. The confusion is old and famous enough to have its own test case, Alanis Morissette's 1996 single 'Ironic', whose examples are still argued over.
