If you’ve ever tried to do the washing and hang it out then I’m sure you’ll have met Murphy’s Law.
For example, if you decide to risk doing the washing on an overcast or cloudy day then by the time the washing machine releases it load back to you (regardless of how quick a cycle you use) then it will have started raining. You’ll have a huge pile of washing sitting there waiting for you to come up with Plan B urgently.
If you feel particularly brave you can put the washing on when you’re about to go out. Even on the most brilliantly sunny day if you choose to put your washing out it will rain. If you choose not to then it most definitely will not rain or even be cloudy all day and you’ll kick yourself for not putting it out.
