I received the bad news in a Department Notice titled "Walk for Water Postponed Due to Rain."
Clicking on the link I found this:
THIS EVENT HAS BEEN POSTPONED DUE TO THE WEATHER FORECAST.
The annual 6k Walk for Water helps raise awareness about water issues worldwide and here at home in D.C. All are welcome. This is part of the Department of State's worldwide Green Race initiative, which uses outdoor activities to raise awareness and stimulate action to help surmount environmental challenges. Walkers follow the Potomac River to the House of Sweden in Georgetown, where environmental nonprofits will be sharing information and have interactive booths. There will even be a giant inflatable toilet, so don't miss the fun. You can also get updates from Twitter (@StateGDI and #6kwaterwalk). Please note that we are trying to reduce the walk's environmental footprint, so bring your own water (preferably in a reusable bottle!). You can refill your bottle at the Swedish embassy.
What sense does it make to postpone because it's raining? Instead, why not declare victory and party in the rain all day long? We should even flush our toilets for the sheer fun of it.
My (rain) hat is off to whoever wrote that title. It falls like steady drops of irony which join into rivulets of humor before combining into a steady stream of paradox and finally becoming a raging torrent of sarcasm.
