Hi my name is Paula Strada and I am a junior at Penn State. One phrase I heard a lot growing up was "don't cry over spilled milk." This phrase is used when something happens, usually and accident, and someone gets more upset than the situation calls for. By saying "don't cry over spilled milk" you're asking the person to calm down, and realize that it's not something to dwell on. This phrase is common between adults and children. Children tend to get upset, or even cry, when they make a mistake on accident and don't understand that adults will not be upset with them. This phrase helps the child calm down. I still hear this phrase as an adult as well. As a stressed college student its easy to get upset about little things that don't go as planned. http://www.cnn.com/2012/07/05/world/europe/qmilch-milk-sustainable-fashion/index.html This link is to an article on CNN about a designer using fabric made out of milk instead of water. There no need to cry over your spilled milk now because it could be used for an eco-friendly fabric!
