The interesting thing is, some spirits come back to "visit" and some don't...both animals and humans. My father's brother appeared to him about a month after the brother's death...and they could never STAND each other! The brother had only one thing on his mind: he wanted to know if his money was going to his children (my father being executor of the will). They didn't like each other any better after my uncle's passing than before!

This uncle of mine apparently was not changed much at all by his sojourn in the hereafter...at least not if my father's version of the incident was accurate. He was just as crabby and demanding as before.

And by the way, my father has never believed in stuff like that...and he showed no inclination for or interest in stuff like that after that incident either! This physical existence remained his sole area of interest. But he did report the apparition to me and my mother the day after it had occurred.
