Another thing about being stubborn: I have this water filter pitcher that I keep in my fridge, because I like drinking really cold water. Sometimes the pitcher has what I perceive as a glass of water left, but sometimes I’ve underestimated a little. In those cases, I pour the water into the glass, and continue to pour, EVEN AS THE GLASS OVERFLOWS. Instead of leaving that little bit in the pitcher. Because if I do that, then the pitcher wins.
