Didn't know your personal feelings. So it's noted I take a comic for what it is a vague commentary on life. For sure you are right in what you described but I was just using the xkcd comic to shed light on the balance between a perfect policy and the human factor that you always need to consider and maybe weaken your policy for. I guess you consider it low brow humour and I apologize.
Also thanks for the added info via psych analyzing.
EDIT: Just giving an update the presentation went well everyone enjoyed it and luckily for me I was able to connect my presentation with the adobe leak of passwords so everything explained itself wonderfully. We discussed bad implementation of secure protocol basically via Adobe. All in all I would like to say thanks to everyone who posted , it got me in the right mindset to discuss a topic I've only just started to truly grasp.
So thanks again.
