Wet washing

why is it that when you don't have a tumble dryer and you need clothes and you put a load of washing on the line to dry, it rains?
I try hard to be an optomist, aparently it takes less energy, but I have to say that since I've moved to Hull I feel the weather has taken against me.
I put the aforsaid load on the line on Wednesday so that the children may have clean underwear. I'm indoors doing some housework and I look up and its tipping it down, absolutely raining lions and wolves never mind cats and dogs. So I recon I'll leave it there on the grounds it may well dry up and be ok. It was in good company, both neighbours also had washing on their lines and it too was wet.
Yesterday morning the weather was dry so I left the washing thinking it may dry, again, before I had chance to get to it, down comes the rain.
Finally today I gave in and bought the washing in, re-washed it and and spun it then hung it on the radiators.... so you can guess what's on the top of my wish list this month????
