Why is it that precipitation holds off all day, UNTIL you need to go outside?

So worked all day at the factory, no rain. Buzzer sounds end of shift, walk out the door and into a nice deluge of rain drops. Ordinarily, this wouldn’t be a major issue.

However, you’ve been notified your daughter’s car is ‘broken down’ and you, you lucky dog, you get to go deal with it…

…IN THE RAIN!!!

Happy-Happy, Joy-Joy.
