Will you get bad luck if someone cross you?

The belief that crossing someone will bring bad luck is a superstition and varies across cultures. Many people think that negative actions can lead to negative consequences, but there's no scientific evidence to support the idea of "bad luck" as a direct result of interpersonal conflicts. Ultimately, how one perceives luck can be influenced by personal beliefs and experiences. It's often more constructive to focus on positive actions and relationships rather than worry about potential bad luck.
