Name two examples of customs that have endured despite their absence in the constitution

The answer to this question is President can only serve two terms and the cabinet.
The term limit of president position is first brought up in the articles of confederation in Article V that mandated "no person shall be capable of being a delegate for more than three years in any term of six years"/
This limit s not directly written in the constitution and now the number of years have changed from three years into four years.

Ifeel like this means that we shouldn't just live for ourselves.also, we should respect others as well as people around us. it reveals that everyone should have equalized freedom, no matter their differences: races, cultures, skin color, etc,. we all deserve the same privileges.
