This is what happens when it rains on laundry day.
Added bonus: we were leaving to go out of town the next day, so I actually needed everything to be dry rather quickly.
Don't worry, everything dried and we got it all packed up for our trip. I never did figure out why it was raining during hot season. It actually was 65 degrees the next day. I've been told that it's one of the coldest days anyone remembers experiencing in Bangkok in the past 10 years.
