What ever happened to good old fashioned morals?

I am trying to raise my children to be thoughtful of other people. To not be greedy, Be kind to all living things (except mosquitoes). To have good manners, like hold the door, offer a seat, please and thank you and to ask before you take something. I feel even at 4 years old my son already has a good grip on this concept and he makes me proud everyday for it.
So how come my 4 year old knows the difference between right and wrong, yet other ADULTS in my life seem to be completely oblivious to these same common courtesy's!

I recently had something stolen from me, from people that I thought were honest and trustworthy. From people who I foolishly assumed loved me and would not purposefully hurt me?
This kind of behavior has had me reevaluating my open and trusting personality? How can I believe that the people within my own close circle are......kind and honest, is it naive of me to want the world (at least my world) to be Peace, Love and Happiness? This is what I wish for my world!

I watch the new, I read the papers, I know the world I filled with people who have no conscience, no morals, no common courtesy's for others..........
This has been a sad and tough week, reflecting, contemplating....
This is a trial of my forgiving nature.......
How do I teach my own children to have a good moral base and to be trusting and forgiving, when I myself am now in a moral conflict?
My hope is my true nature will prevail and I will have learned a lesson from this experience (although I am not yet sure what that lesson could be as of now?)

I am hoping for strength and peace!

July 29,2010: Strength and Peace at Heart!
During the year since I wrote this post I continued to struggle with "forgiveness".  I had a hard time trusting people, even people I love and trust.  I felt as though for awhile I had a nagging feeling of sadness that always lingered in the back of my mind.....then if you can believe it I learned a life lesson from a movie Amish Grace it is a Lifetime movie.  In the movie Grace learns the Amish way of forgiving is to let all feelings of hate and anger be given up to a greater spirit (in this case God), in my case Karma.  I learned that it is not good for your heart to hold on to negative feelings and sadness.  I now believe if you let it go.... the person you hold such feelings for will have to eventually answer to a higher power, or their own conscience.  So LET IT GO and trust that justice will manifest in some form. I actually am grateful for this experience now, it has helped to to let go of allot of pent up feelings I was holding from years past.......
I also know that Karma has come back to me for times I have hurt others. (I do believe that this experience is do to my own past actions). 
I  feel sorry for those who still struggle with living without kindness and a moral conscience and hope that one day they will learn to listen to their heart.nds herself struggling with her community’s belief in the transcending power of forgiveness.herself struggling with her community’s belief in the transcending power of forgiveness.
