My room here in Zambia has a tub with a hand shower. Which would be fine, except that the shower head doesn’t reach above knee level. Looking on the bright side, I suspected I could get some awesome stretches in as I bathed. I was ecstatic when I opened the taps and warm water flowed from the tap. I pulled the knob to create the shower flow, and water trickled out the low shower head. Cold, very, very cold water. Had I run out of warm water that quickly? In a matter of seconds? I pushed the knob so that water flowed from the tap. No, it was warm. This went back and forth for several minutes. Cold shower? Warm bath? After a mere moment’s consideration, warm water trumped.
