I was raised that way.

Those of you who grew up here in the United States where they promote "freedom of speech" have the tendency to just say whatever and and as time goes on you learn to watch what you say after putting your foot in your mouth enough times. When you grow up in cultures that dont practice that freedom of speech it's the opposite way. You start out watching what the fukk you say. Then over time as you get older you learn to take more calculated liberties in expressing yourself.
Thus why you got american kids talking back and cussing their moms by the time they turn 16+

In other countries you talk back ... well you wouldnt even dare to talk back because you been conditioned not to...
