That you can do something, because it's your normal and yet:
some can think (before they get to know you.) that you are acting within a drug use (state of being) and yet,
it's because they see others acting and being active users of a drug:
as that is what brings them to that point in being willing to question you upon your actions.
So it may be your normal: yet, if you have been a drug user for so long, then who are you; who are you, when you stop using: for you have lost yourself and now have to learn how to live within a sober means of it being okay to be board.
