The most important thing for us to do when someone meets us is to assure that they know what lines not to cross with us. In these modern times respect, consideration and friendship all are being washed away and replaced by intimidation, belittlement, and harassment.
It is YOUR duty to stop a person in his or her tracks when they start to "feel you out" in the beginning of your association with them. Don't allow them to suck you in with jokes, impressive stories, gifts, promises etc... Keep your stance solid by showing respect, remaining professional and stepping away from them as soon as they try to cross any lines.
Never value anything that someone has to offer you over your personal integrity or you will pay them back with way more than you will ever get from them. YOU are under YOUR personal protection. YOU are YOUR PERSONAL BODYGUARD!
And THIS, ...is a "way" of the "Warrior's Edge"
