no, you.

The age old question of, "I know you are but what am I?"
By the time you reach 25, you tend to do this slightly less. However that's only because it gets replaced.
You find you'll start saying, "you're projecting." It means exactly the same thing but is somehow more acceptable. helped no doubt by House.

Funnily enough, as any poker player will tell you, you project all the time. Usually subconsciously.
For example, you like to bitch about people at work when you're frustrated, so you expect others to do likewise. In fact, when they don't, you become concerned for their mental well being.
of course, you're just projecting your attitude on to everyone else and thinking if they don't think the same as you, they're bad. and that is a surefire recipe for disaster if you're a poker player. unless you're a bad poker player, when most other people do actually think like you. except you will still lose because you're bad.
