Sadly, the father may be physically absent through separation, divorce or death, representing elusiveness and inaccessibility. There can also be a deep sadness around him, and he may be unobtainable to the person physically and/or psychologically.

Sometimes a gentleness and ethereal quality are terms used to describe the father.

Another thing to watch out for is Neptune's slippery boundaries and often around deception. They are prone to being gullible, and inviting (out of sympathy or pity) others to stay in their home, be aware of those taking anyone taking advantage of such kind hospitality.
