structure
A relationship set is a set of relationships of the exact same typu
The possible relationships between two sets (here arbitrarily named A and B) are:If each element of set A is also element of set B (and vice versa), the two sets are equal.If no element of set A is element of set B (and vice versa), the two sets are disjoint.If all elements of set A are also elements of set B, the set A is a subset of set B. If set B contains elements not found in set A, the set A is a proper or strict subset of set B. Set B is called supersetresp. proper superset of A.If set A and set B share some elements, but each set also has elements not found in the other set, the two sets intersect.

well at a young age you are not at the best mind set to be in a real serious relationship.
Fundamental relationships
A set within a set, often referred to as a subset, is a collection of elements that are all contained within another set. For example, if Set A is {1, 2, 3}, then Set B = {1, 2} is a subset of Set A. This relationship indicates that all members of Set B are also found in Set A, but Set A may contain additional elements not present in Set B. The concept is fundamental in set theory and helps to understand relationships between different collections of items.
