"There are two kinds of people: the ones who have to be told, and the ones who figure it out all by themselves" - Tom Clancy

I'm pretty sure there are more than 2 kinds of people.

True, there may be
1) The ones who have to be told, and
2) The ones who figure it out all by themselves......but there are also...
3) The ones who had to be told, but later on when asked to do it again, had to ask again....
4) The ones who were too intoxicated to remember what they were told.....or completely rearrange what they were told..
5) Assholes: Who, no matter how many times you tell them, they won't believe you.

This list is endless.....but I think you get the idea......and if you don't, you are technically a #5~
