I was bullied at secondary school back in the days when schools seemed to turn a blind eye to it - or where it was beyond the school's control, as a lot of it took place on the school bus where there were no teachers, and I couldn't get away from it (at its worst, in the case of one particular boy, the way he behaved would be classed as sexual harassment if it was happening between 2 adults).
I always tried not to play the victim, never answered back, never fought back, used to walk away (if not on the bus) and go to the library where I wouldn't be followed. None of it stopped the bullying from happening. I was in despair most of the time not knowing how to avoid it - I didn't care about being 'popular' or fitting in, I just wanted to be left alone and get through school as invisibly as I could.
Not sure if I have a conclusion here, but I was left feeling that even when trying not to behave like a victim and respond to their behaviour, I must have still given off vibes that I was vulnerable and unhappy that made me an easy target. So perhaps it's not about saying 'don't behave like a victim and you won't be one', it's more like 'everyone is vulnerable in some way or other - let's help you find ways to protect your vulnerable side'.
I must have developed a thick skin somehow as an adult as my first ever boss was a terrible bully and her meanness somehow made me more determined than ever to succeed in the job and I was really proud when I eventually won her respect and walked away from the job with my head held high.
However last year I did come across a person whose behaviour I just couldn't cope with and all my childhood instincts came back - I had to leave my career rather than have to work with this person and am not sure I'll ever work professionally again, it was that bad. However, I don't regret the decision (though I miss the money!) as I'm now doing unpaid work which is much more fulfilling.
