Further Experiments with Postal Karma

Ok, so in our last episode, I had delivered the movie-less Netflix mailpiece to the already upset postal customer Mrs. V.
A few days after that adventure, I came face to face with the usually not-at-home Mrs. V.
She was picking up her blue recycling bin from the curb when I came into her yard.
I offered her a sunny HELLO and in turn receiver a big fat nothing!
Two days later, she got a card mailed back to her that she had sent out with a non-existant street name on it. I knew the person she was mailing the card to ( a very nice teacher of mine from high school).
I was faced with a moral dilema.
1) Do i smugly stuff the letter back in her box and say to myself "See Mrs. V..sometimes it's not the dear old PO that screws up..."
or
2) do i dig deep and listen to my higher angels, bring the letter back to the PO, correct the address and send it on its merry way?

I went for option #2.
Now I am waiting to see if that secret act of kindness will be able to magically turn this embittered customer around.
