Word game :- Sweet/Sour
Sourest Day is observed annually on October 25. Following on the heels of Sweetest Day, this is the Sourest Day of the Year.
If life is giving you lemons or you feel like a grumpy guss, Sourest Day is for you. Take your glass-half-full attitude and spread the joy -er- gloom. Smiles be banished! Replace them all with pouts and terrible frowns.
