Makes one sad when read in good times-Riddle

Riddle

Once while in Kushal's house, he asked Riya to write something on a wall that makes one sad when read in good times and makes one happy when read in sad times.

    She writes: "The time will pass soon." If you read this line in happy times, you will be sad because you would want the happy time to last forever. If you read it in sad times, you will feel happy, as you will feel optimistic about the future.
