I don't feel the same about drinking water from a friend's filter or at a restaurant as I do with my Dasani because it's not MY water. I don't feel the same about washing my hands and brushing my teeth in a sink outside of my home because it's not MY water. I don't feel the same showering outside of my home because it's not MY water. I know it's foolish, but does anyone else feel a bit more anxious when it's not your water?
