Despite your situation you have the ability to choose to make youself into something other than the sterotype that is punched out of the moulding of the social norms. At at the very least, don't you choose which norms you adhere too? I mean, pot smoker rather than "law-abiding citizen"...

Obviously our choices are constrained by our situation, but we can always resist social norms, rules and laws if we feel so compelled.

If you could change into something (someone?) else, what would you choose to change into?

Is free-choice really in question?
