Why does everybody were poppy's?

The phrase "everybody wore poppies" typically refers to the tradition of wearing red poppy flowers to commemorate soldiers who died in military service, particularly during World War I. This practice originated from the poem "In Flanders Fields," which highlights the poppies that grew in battlefields. Poppies have become a symbol of remembrance, especially around Remembrance Day or Veterans Day, as a way to honor and remember those who sacrificed their lives for their country.
