Neighbors are often responsible for taking care of each other's yards and gardens while mowing their lawns, so when one neighbor destroys another's flower bed and kills all the flowers, it is considered to be an act of negligence and nothing to cheer about.
Consider the statement "A neighbor mowed over my flower bed and now of my flowers were destroyed.". Based on this "Cheerful about how a neighbor destroyed my flower bed and killed all my flowers when they were mowing their lawn" a true statement? Yes, no, or I don't know?
