It is almost universal that a slave kneels when entering her master’s presence
It is almost universal, as far as I know, that a slave kneels in one fashion or another when entering her master’s presence, or if she should find herself in his presence. She also commonly kneels when spoken to by any free person. This is simply a matter of respect. To be sure, she can be slain, if she does not do so. The kneeling position, of course, which the master’s, or free person’s, permission, either tacit or explicit, is usually required to break, is commonly an initial position. For example, after its deferential assumption, she may be dismissed from it, to other duties, such as cleaning, shopping or cooking.
