I prefer to play by the rules until caught. My grandfather told me quite a few times "It is sometimes easier to get forgiveness than permission" I carried a knife to school once when very young (2nd grade) and it was taken away from me and given back to my parents. I was not allowed to carry and use a knife for a long while after that.

In high school I carried a Leatherman everyday, until the principal found out about it and he and i had a conference in his office. I was told not to bring it back to school and therefore no one knew when i started carrying it again or about the small pocketknife I carried. If you don't advertise then no one will know.
