I read your reply while lying on my couch enjoying an enforced day off…due to rain. Now that I think of it there is an association with rain I have always found soothing… the sound of it. It is, like the sound of the sea or the wind, an ancient sound. That is, time and technology have not altered it in any way. What a person heard in their dwelling or in a forest ten thousand or a hundred years ago when it rained is what we hear today. It’s not for nothing that they include the sound of rain as an option in those sound generators that are popular today.
LOL, I will freely admit that rain sounds quite different when laying in a hammock smoking a pipe, than it does when you are laying under a car trying to fix the brakes as the rain runs though your clothes in its journey down the driveway past you!
