I finally got a friend into magic, and he's getting really good fast. I've been doing magic for a little less than four years and him less than a year. We both want to do some flourishing, and we were looking at part two of the Trilogy with the Bucks. The moves look like they will take some practice, but anything can be accomplished with determination. What I was wondering if it would be ok for both of us to pay $15 and share the DVD. Would this be considered unethical? Thank you for any input.
