Couples, sweethearts, and people who want to express their love for someone give chocolates, flowers, and all the sweet, merry gifts you can think of on Valentines Day. If you didn't have someone to give something to, then you just go on with your life. But back in the 1800s, people were more up front with their feelings, even to those they hate.
If you detested someone so vehemently, then you would give them the opposite of what you would send your lover or a sweetheart. These are called vinegar valentines or comic valentines. People did not hold back what they thought of their sworn enemies. From subtly rude to downright, blatant cruelty, these vinegar valentines are relentless. Whether it be rejection or creative, verbal insults, they don't hold back on anything.
