Non-violent/violence-light pen and paper game/rpg?

I'm going on a trip with some friends for school and they want me and my friends to "bond and have social interaction". Anyways I won't have my trusty iPhone for use during that time. I came up with the idea of playing a Pen and paper rpg with them. First I tried Call of Cthulhu with them at school, but it was shut down by teachers who claimed it was "violent"(I know right, yawn extreme). So I'm looking for a pen and paper rpg/game with a narrative point of view, a good character development system and action system where violence and killing aren't a central theme. I want to specify that by non-violent, I don't mean if there's anything bad we will be shut down, I just mean that there shouldn't be very long action sequences. Short ones are fine so that they can be committed out of earshot of any adults (which will be the case most of the time).

Actually there are many such RPGs choose your favourite one from the website. Enjoy!
