Personally, I like rainy days. At least, as long as you can take an umbrella and still get out to enjoy them. There's that smell of rain, actually created by a type of bacteria (or so I've been told), and the harassed looks of people trying to get from point A to point B.

The expression is interesting, though a bit misogynistic. That's one I haven't heard before.

"A mala lluvia, buen paraguas" is one I heard in southern Spain. "For bad rain, a good umbrella."
