Yesterday evening my DH realised that the washing that had been done the previous night was still in the machine. (He should have hung it out as he was WFH and I was in the office). So at 6pm he hung it out. 
I TOLD him not too as it would get darked on, but he insisted. 
This morning we got up and it was raining. He said 'There, everything will be fine, the rain will have washed off all the dark AND where the spiders willies have rubbed. No need to re wash it'
Dilemma: do I believe him or do I re wash?
