A grudge is a persistent feeling of resentment or ill will towards someone due to a past offense or perceived wrong. It often arises from unresolved conflicts, leading individuals to hold onto negative feelings instead of forgiving and moving on. Grudges can affect relationships and mental well-being, as they may cause ongoing stress and bitterness. People may carry grudges for various reasons, including betrayal, unfair treatment, or personal slights. Holding a grudge can hinder personal growth and happiness, as it keeps individuals focused on past grievances rather than fostering positive connections. Letting go of a grudge often involves forgiveness and understanding.
