Now, I suspect you scienc-y folk will give me a knowing and ever so slightly condescending look as you tell me that there is, in fact, no qualitative difference between water heated by sun and water heated by electricity. But I assure you there is. I do have an electric back-up switch, which has been called upon on rare occasion, and it is just not the same. Its harsh. Metallic. Cold, though its scalding hot. Sunjuice, on the other hand, is warm and embracing, gentle even if you need to add cold so as not to get burned...
(The only down side to my shower bliss is the mornings I wake up and find a spider or spiders (!!) in the tub... Last week I had to forgo a shower altogether one day due to a very LARGE spider that was stuck in the tub. Thank you Molly for helping me escort that particular unwanted visitor off the premises later that evening...) (Ok, maybe he was midsized... but he definitely wasn't going to fit down the drain holes... which required removal out of the tub from above. And I don't squish things bigger than mosquitos. I'm not that kind of tough.)
