Ha yes, who would think we'd learn that specific interaction game better than those who made us play it, or that you'd grow to love the game, and be unable to stop playing? It's not fair that by using the same game to protect yourself from bullying, you end up making them the victim, and then you feel guilty about it. After all, that's what they were trying to do to you!
Heh, I should point out to you all the manipulations. I can see them plain as day.
Evoking sympathy: Show a bit of emotion, using strong evocative words like "hate". Then speak about how its a part of you. People will get the feeling that you hate yourself. "I am aware of the damage I caused them".
Of course, there's the ego part. Make yourself seem smarter than you are: "I used to employ it often", "other such tactics", "I fostered that view", "They have learnt what I did at an early age". All manipulations to portray myself as smart and devious.
Then, there's the fact that I do manipulate as I used to, and people know this, instead of making it a definitive statement and making it seem as if I'm lying and trying to make myself sound better than I am, you put words that show you aren't infallable, that you're not omniscient. Not only allows people to empathise, but also plays on the sympathy card, and makes the statements easier to believe: "I have tried to change", "Now I try only", "there are the occasional relapses", "I don't think".
And then of course, there are the statements to make me sound altruistic: "Now I try only to make them feel better about themselves, and to act as a support.", "It can sometimes really help people to let them know that they can help you."
The absence of manipulation exists only in silence, and even that can be used to good effect in certain situations.
