As the group decides how it wants its meetings to run, and what are appropriate standards of behaviour for group purpose, it will make agreements or rules or guidelines which it is expected each group member will follow.

These allow the group to function normally and purposefully, and restrict the possibility of any one man to upset (or in extreme cases even destroy) the groups ability to function. The desire is to contain interactions within a safe space and to support healthy/appropriate self-expression, and to exclude actions that are shaming or otherwise abusive and harmful.
