i think it largely has to do with the personality of the person who is going to be ignored. If Master were to ignore me, that would be an EXTREMELY severe punishment, so if it were given out i know that i would have had to something pretty extreme. Because i know how badly it would hurt to feel cut off from Him, even if only for a short amount of time, i would never put myself in a position to endure this; likewise, because He knows how badly it would hurt me, He would never spring such a punishment on me for something that wasn't a big deal. i think that this issue really just depends on the personalities of the people involved, and as long as there is communication on both sides, when/if such a punishment occurs, it will not be harmful to the relationship.
