Secrecy
Some secrets are good. These are ones that should be kept secret. An example of a good secret is respect for a citizen's privacy.  But some secrets are bad, if keeping facts hidden causes harm. An example of a bad secret is child abuse. Some things might be kept secret only for a short time, such as a surprise party. Other things may need to be kept secret forever. Sometimes things might be kept secret from someone because it is believed that it would upset them to know.
