When I was in South America this past summer, it was practically impossible to find a hot shower. Mind you this was the continent's winter, so upon waking in a freezing hotel room, all we wanted was a warm shower. Not the case. In many countries, a hot shower is unheard of, a complete luxury. Coming home after my trip and taking a warm shower (with water pressure) was pure bliss. For that, I am thankful.
I would love to hear about the simple things about which you are appreciative.
