It was a bit of a challenge to wrap my head around, David is a southpaw, I am not. So, it made for excellent viewing,  because I could see what he was doing.

However, trying to follow along from the right was some thing I had to work through. 

I followed along, but like David mentioned in the video, there were places that I didn’t feel comfortable or know enough about the theory to execute confidentiality.

Excellent class, you are a good teacher Mr. Finch, thank you!
