What is the saddest fruit?

Common Wrong Answers
“Banana”
Bananas are often associated with happiness due to their bright color and shape, making them an unlikely candidate for the 'saddest' fruit.
“Grapefruit”
While grapefruit has a somewhat bitter taste, it is not commonly associated with sadness and does not fit the riddle's context.
“Lemon”
Lemons are often associated with sourness and can symbolize bitterness, but they don't directly connect to the concept of sadness as strongly as blueberries do.
