people might ask why they fly and dont land or why they act so crazy...

there are 10 things that could make an intelligent creature act crazy that people will not understand it...

1. IF you had a super memory...you will remember things that nobody does, thus you will act crazy, your behavior will not be normal...

2. YOU COULD SEE MICROSCOPIC THINGS...again it will make act crazy/odd/strange...

3. You could see ghosts...again it will make act crazy/odd/strange...your behavior will not be normal...

4. IF YOU WAS A PSYCHIC...again it will make act crazy/odd/strange...your behavior will not be normal...

5. IF YOU COULD READ PEOPLE´S MIND...again it will make act crazy/odd/strange...your behavior will not be normal...

6. YOU HAD A SUPER, SUPER HEARING...again it will make act crazy/odd/strange...your behavior will not be normal...

7.   IF YOU WAS TALKING IN CODES...again it will make act crazy/odd/strange...your behavior will not be normal...

8.  IF YOU COULD TALK TO ANIMALS OR READ THEIR MINDS...again it will make act crazy/odd/strange...your behavior will not be normal...

9. IF YOU WAS FROM THE FUTURE...again it will make act crazy/odd/strange...your behavior will not be normal...

10. SOMETHING SO SIMPLE AS HAVING YOUR 2 SIDES OF THE BRAIN UNITED [YOU know both of the sides of your brain are separated by a ridge i think is called, i forgot what is called]...again it will make act crazy/odd/strange...your behavior will not be normal...
