“Dogs return to eat their vomit, just as fools repeat their foolishness.”
When ever our fellow man falls we should help them up at least once. If they do it again we still need to help them but may be our tactics should be different the next time. There is a difference in helping and enabling. Sometimes a supervised fall to rock bottom is what is needed to help them. If you enable someone to destroy them self to long then their may not be anything that can be done in to help them.
