National Don't Cry Over Spilled Milk day

The phrase "Don't cry over spilled milk" is a common idiom that is used to encourage people to move on from small mistakes or setbacks, rather than dwelling on them. The origin of the phrase is not entirely clear, but it is believed to have originated in the United States in the 1800s. One possible explanation is that the phrase is derived from an old proverb, "No weeping for shed milk", which dates back to the early 1600s. Another theory suggests that the phrase may have originated from the practice of farmers who would sometimes spill milk while milking their cows. Instead of becoming upset and wasting time lamenting the spilled milk, they would simply move on and continue with their work. Whatever its origin, the phrase has become a common way of encouraging people to let go of small disappointments and to focus on more important things. It is often used in a lighthearted way to remind people not to get too upset over minor mishaps, and to keep things in perspective.
