Most of our stereotypes are originated from a few tendencies that we have.
Iranian parents actually sacrifice themselves for their children's education,
and an Iranian immigrant never spends all of his/her money in the way
western people do,but invests it to diversify his/her income sources.these
two cultural elements makes them rich in industrial societies,so people
think they all are "filthy rich".Also,Iranian consider their social image very
important.so,they use best of dresses,use a lot of perfume,women use
intensive make-up,and girls endure hard exercises to look hot.Unfortunately
we tend to deceive other people and trick them,normally with making
friendly faces and act like an old friend,until the last moment of final blow.
Never ever you should do anything insulting to an Iranian,specially calling
him/her an Arab or slurs for them like sandnigg*r or so,because he/she
never forgets it and never changes his friendly face,but contemplates a
devilish plot against your public image,mostly executed by the target
I'm a Persian.
