Letter from a former slave

I found this letter in a news item from Yahoo. I have no idea if it’s authenticity has been determined. However, it does display the resilience and strength of people that were at one time treated as chattel. I especially appreciate the humor.
It’s important to note that at no time does the writer indicate that he wished to take retribution for the treatment inflicted on him and his family. This is one point that I have seen reiterated time and again by the womanists. While they have strong feelings about justice for everyone, there is never an indication that revenge is an option.
Please, take time to read the letter:
