I have to say not at all.Primary was fine,I was then a bit of a Tomboy and used to get into fights with some of the boys etc,no one bothered me,the girls didn't even try.My secondary school was an all girls convent school,the bleedin' nuns were the ones to watch out for!
Saying that my younger sister is six years younger than me,so I was in my final year of primary school and she told me that a girl that was a year older than her was picking on her,pushing her,pulling her hair etc.All I did was confront said bully in the playground and state that if she touched my little sister again I would go for her ( not that I would) the threat was enough.
