I applaud your valiant effort to help the users; However, sometimes they are best helped by putting a bullet in their head.
In jest about work
The boss will tell you that nobody is indispensable. When you ask for a promotion, you will be told that you are indispensable in your current post..... making you... a nobody
Being Idiot proof
Idiot proof is impossible; it requires an intelligent being to think like an idiot which any idiot can beat by sheer experience and idiotic tendency
Anyone can come up to you tell that you always have a choice; but they will not tell you its between the blade and the deep blue sea
