People confuse the hell out of me. Let me pose a situation to you, then a list of reactions.

Situation A: Your walking down the street, and someone gets hit by a city bus, thrown 50ft into a cart of watermelon. You, being a rational, sane human being...

1) run screaming that the aliens are trying to kill us while donning a tin-foil hat
2) call for an ambulance immediately while administering first aid to the injured man
3) stand there mouth agape and utter a very neolike "whoa..."

Now, I could see at least 2 of those being normal reactions.

Situation B: Your boss calls everyone into the office one day, and announces that he is leaving the company. The only possible indication of this was the number of memo's floating around the office asking odd questions. Later you find out he was causing a severe number of problems with other upper management, and was trying to get a bunch of co-workers fired while simultaneously taking over the company for whatever plans he had concocted. You, as a rational and sane member of the company...

1) decide that boss was the only reason you came to work, leave the company in a huff, and make a few speeches about how you like everyone, you just don't want to be around them anymore
2) Go back to work, and hope the new boss is better than the old one
3) come up with odd conspiracies with the other coworkers around the water cooler for about a week, but end up going back to work regardless.

once again, 2 of these are good reactions, and one is what a crazy person would do. Mind you, these incidents may or may not have any bearing in real life, but should be a cause to think. There are people out there that would have considered the 'crazy' options completely viable.
