Your first mistake is calling someone "master" when you've only known him for 2 weeks. Your second mistake is transferring the behaviors of your ex onto this brand new person whom you've just met. Personally, I don't think it's your responsibility to come up with a punishment, but since he doesn't really know you or know what would work....how about writing an essay on what his expectations of you are, how you failed to do what he expected, and how you plan on acheiving what he expects of you in the future....or is that too much?
