in my experience, i would say that if the gentleman was actually going to do you harm, then he's probably already prepared for whatever violence comes. by brandishing the weapon, you've tipped off the attacker to what you're holding, what hand, etc. at least in ero-sennin's anecdotes, he made sure to conceal the blade. also in my experience, predators are trying their best to not tip their prey off. and most likely, work in teams. yes, i disagree. aside from the fact that you haven't established any actual danger at all, except some perceived threat. but you escalated for no reason. in my opinion. there are mentally ill people out there. you brandishing a blade may make that person think you're the one that's a danger to him/her. next time that person sees you on campus, how do you think he will react? i'm glad you're safe. i just don't get the anecdote. i also wonder, and this is what i'm getting at in my previous comment about "you've figured it out"...you first ask for thoughts/comments, but when someone actually does have a thought, you put out a detailed decision tree of this and that. are you sure you're asking for feedback? or just looking for someone to tell you you're right?
