the other fun one is when you have cleaned up your act. Your now far far far from the person you once where. Your attitude is different your different your life is good etc.. its all entirely different. then you run into an old friend from back in the day. and the underlying tone of the conversation(s) is as if your still the person you once where and your not. Though all they see is that person from way back they have no idea who the new you is etc..
Having had the above situation play out it stinks becuase in the end I just couldnt keep talking to this person there was nothing fruitful coming from it and i felt as if all it did was drag me down.
sometimes you just gotta get new friends.
