We needed the rain at this time

Da classic bu**s**t remark dat people use to try to make each other feel better regarding an unforeseen/inconvenient downpour.

Everyone's lawns and gardens were flourishing just dandy before today's torrential downpour, so why is everyone telling each other, "We needed the rain at this time"?! Who needs drenched muddy sidewalks and huge messy puddles all over town???
