I had never heard about Sweetest Day until I went to school In Michigan. It started out in the Midwest but is now becoming popular all over.
Sweetest Day supposedly started during the Depression. A guy who had barely lost in money in the crash and wasnt doing too bad thought it would be nice to just have a day where people helped each other out. The guy and others helped out homeless people and more, so the day became Sweetest Day. Your being Sweet to others.
However somewhere down the line it got turned into a Hallmark Holiday and now its the same damn thing (bitter...YES!! ) as Valentines Day, just later in the year. Girls can exchange stuff with guys and guys can exchange stuff with girls. And even though im a girl, there probably was some girl who got back at her bf with this and its how it got started. Same with Valentines Day, cuz your actually suppose tp be recognizing the Saint Valentine and his work.
