This idiom (love idioms by the way).... means that when things go wrong, a lot of things go wrong at the same time. Or sometimes it goes in three's, which I'm not sure if thats a good thing or not lol. I'm also not sure if its ironic or not that it rained SUPER hard tonight. It rained so hard it poured hail.... but whatever the case.... I do always find when it rains it pours. Good or bad. Happy or sad. Great or small. When it rains it pours.
I do prefer dryer climates. (wink wink)
