I grew up in Germany until I was a teenager, and even though I've lived in the States for about 34 years, I'm still in culture shock. I take off my shoes by the front door, turn off all the lights in rooms I'm not in, don't run water while I brush my teeth until the end to rinse the brush, drink lager beer, and only dip my fries in mayonnaise like the Lord intended.
Maybe that's why I don't waste running water in the shower?
