Regardless of the size or the purpose, every group has similar characteristics:
- 2 or more persons (if it is one person. it is not a group)
- Formal social structure (the rules of the game are defined)
- Common fate (they will swim together)
- Common goals (the destiny is the same and emotionally connected)
- Face-to-face interaction (they will talk with, each other)
- Interdependence (each one is complementary to the other)
- Self-definition as group members (what one is who belongs to the group)
- Recognition by others (yes. you belong to the group).
