Rain, rain go away come back another day or better still come back another night.
I know how you feel...living here in Northern Ireland it sometimes feels the rain is never going to stop. I expect you should really try to be happy that you’re getting some rainfall in Australia, because the lack of rain has been a really serious problem for you. Of only it would come when we want it to...as you say nighttime ideally!
Yes, we do have problems with lack of rain in some parts of Australia, especially in summer. Another huge problem is that the big irrigators "steal" all the water from the rivers so they die. All courtesy of our corrupt government.
