Karen is a conversationalist and uses gray water collected outside the home, in the sinks and in the shower, to fill the toilet back. I personally admired this and kept my usage to a minimum. I am a bit of a hippy and water scout as well, which is why we got along so well, but I can imagine this could be off putting for some so I'm mentioning it. I want to also mention something called "Load Shedding" which happens when the Gov't needs to conserve electricity. They rotate the city's electic power around town by shutting off electricity elsewhere for 2.5hrs sometimes 3x daily. Karen also supplies the data to her home and isn't able to top up if it runs out, so be respectful to other travelers not to download or upload too much at the space.
