I first learned of what revenge was when I was in the fourth grade.  We had just arrived at our new posting, as we were a solid band of Army brats. 

The house we would be moving into was not ready when we got to the base.  To get us through the next ten days, we were put in a two bedroom appartment.  That is two parents and four kids.  We still had fun.

On about the fifth or sixth day we had all rain.  Plus, it was summer, so no school.

A movie sounded great.  There were two showing on base.  One had the word,"Revenge" in its title.  I asked what that meant and my parents spent about an hour with us explaining what it was and why we might feel like getting revenge.  However, they said that revenge was never a very good thing, unless one is protecting themselves.  But, beyond that, revenge begets revenge (no, my parents never used the word, "begets," I just wanted to find a way to use the word.

I have remembered that day and talk for a number of decades now.  I know how bad it can make one's own life, let alone the other/s involved.

I find this quote from Marcus Aurelius, a man who figures highly in my spiritual beliefs, had this to say on the subject:

The best revenge is to be unlike him who performed the injury.
Marcus Aurelius

Be honest, have you ever taken revenge?  Did it give you the satisfaction it had given me at times when I was younger.  Or, did it give a feeling of shame and guilt, as I had when I "got my revenge" on others, when I was a bit older?
