Have something in common

To "have something in common (with somebody)" means to share a particular interest, characteristic, experience, or trait with another person or a group of people. This commonality can serve as a foundation for building connections, friendships, or a sense of belonging among individuals.
Examples of things that people might have in common include:

• Hobbies, such as playing a sport, painting, or cooking.
• Life experiences, like growing up in the same neighborhood or attending the same school.
• Personality traits, like being outgoing, creative, or meticulous.
• Beliefs or values, such as a shared commitment to a cause or religion.
• Preferences, like enjoying the same type of music or food.
• Goals or aspirations, like wanting to travel the world or start a business.

Identifying shared interests or traits can help people connect, empathize with one another, and establish strong relationships, as it provides a basis for understanding and shared experiences.
