1- When you spend ages trying to remember what the fuck it is you were thinking about a second back, and through conscious effort actually remember.
2- When you fail to achieve the norm, because you're lazy, and either you're arrogant (according to others) or you can absolutely see the simplicity of what you have failed to fucking achieve (and know it is beneath your abilities) thus making it ridiculously boring and not worth the initial effort. Except you know, you know, that you should have put in the effort for your own good, essentially making you an idiot, which can make you feel terrible.
3- Your sense of direction could be surprisingly terrible.
4- You lose items on an occasional basis, but always manage to find them!
5- When you get called 'weird' on a frequent basis.
6- You put on a sort of conscious Fe mask, and are aware of your facial expressions and words when communicating with MORTALS. I PITY MORTALS!
7- When you are convinced you are insane, find humor in it, and laugh like a lunatic.
8- When you can't help but use intellect (either Thinking or expressing it) whilst communicating with MORTALS (I PITY MORTALS!) who have an astonishing number of fallacies in several words in just one bloody sentence. Oh, how you want to correct them! Oh, the effort! Oh, fuck it! Nodding is so much simpler. You decide to resort to nodding!
9- When you find yourself doing this quite often - the demeanor of a mad man lost in space.
10- When you are given news about death, in most cases, you either don't know what to say, or say something sympathetic but Feel nothing. You are now probably curious to what has happened to that poor soul, and possess little streaks of envy. (Though, you could feel pretty bad).
11- You can be a surprisingly patient person, because who the fuck cares about linear 24 hour societal clock-time?
12- You delete sentences you have typed because you're not quite sure if you really meant what you have said. Same applies to Thinking something, then Thinking whether to say it or not, then resolve to not saying it!
13- When nothing seems to make any sense whatsoever. (Sometimes..)
14- Your behavior may not reflect your age. Screw 'acting like an adult'. Screw convention. Screw social patterns. Screw politics. Screw social correctness and expectations.
15- Sometimes you find yourself conforming to what you previously said 'screw it!' to - but you are consciously doing it with something in mind.
16- When nothing really seems to matter, strong nihilistic thoughts.
17- You'd much rather be a mammal of your choice. Like a turtle.
18- When you think of the perfect thing to say or think about at the wrong time.
19- You think the new YouTube sensation 'Gangnam style' is relatively stupid as fuck, but perhaps find some humor in it.
