You don't think many people (I'd say women, but Rev will yell at me maybe) grow up thinking about how their wedding day is going to be bright and shiny, and just all around perfect? Do I need to give you a lesson about the 3 types of irony? Because expecting your wedding day to be sunny and then having it rain is a prime example of situational irony.
If I expect to fuck Emily Ratajkowski when I get home tonight (I won't, alas), that just makes me an idiot rather than a victim of situational irony. There's no reason to expect a sunny day over any other kind of day (unless you're in the desert). Hope ≠ reasonable expectation.
