Laura said this to her mother Mrs Sheridan. When Laura heard about the death news of Mr Scott, she tried to convince her mother to cancel the party. According to her, the music and merriment of such an extravagant garden party will be inappropriate to the grieving family members of Mr Scott, a near neighbour. But Mrs Sheridan did not listen to any of this. Therefore, to Laura, who is compassionate and sensitive, continuation of the party would be ‘heartless’. Even though Laura received the same upper class upbringing like her other siblings, she was slightly different
from the other Sheridans. She did not look down upon the working class people unlike other upper class members. Her privileged lifestyle did not turn her into an unsympathetic person who remained unconcerned about the hardships of the working class people. That is why, Laura was upset when she leamed about Mr Scott’s death news and wanted to cancel their party out of respect for the family who had experienced a huge personal loss. This brings to the front her humane feelings.
