Because girls don't really 'bullly' as in shoving and knocking Du down and ect. They talk about Du and make Du feel bad. So I guess that's why there's not enough attention on it. Plus everyone knows how girls are and I guess they see it as normal. There's wasn't really any bullies at my school, everyone was in the same 'class'.
In general, a lot of female bullies attack with words instead of physically beating up someone (note that this is in general, where I am there are a lot of cases of girls physically attacking).
Seeing as words aren't something that can be seen, then this form of bullying tends to go unnoticed as Du can't see that a person is covered in bruises to easily click that they're being bullied.
But then this idea crosses the gender boundary and enters Mehr into physical vs verbal abuse, which either gender is capable of. Because I was verbally abused Von one boy several years Vor that I never spoke up about, which obviously caused it to go ignored (the twat was expelled after a few weeks anyway). But I would say the ignoring aspect comes Mehr from the fact that verbal abuse is easier to hide, and is a form that I have experience from males and females, not females exclusively. Physical abuse is always immediately taken seriously, female oder male, it doesn't matter.
