As adults we have many agreements with other adults. We have agreements that describe the service we are using and explain the relationship between us. The agreements protect us, and ensure good service. Such agreements are especially important when it comes to private and intimate issues, and when working with young adults.
Teachers have agreements
Through their employment at a High School, teachers have agreements that describe their rights and expectations and responsibilities and authorities.
Dentist have agreements
That's why Dentists are allowed to dig around inside our mouths, we have an implicit agreement with them that it's OK to look in an otherwise private and intimate place.
Doctors have agreements
That's why Doctors are allowed to look in places that we normally regard as private and intimate. They have given an Oath that promises their actions have good intentions.
Coaches have agreements
In the same way Coaches need to have a Coaching Agreement that allows them to dig around in intimate places and look at private things.
