Mentioned this one b4, so not gonna say again. But just let me quote something.
"Even though no one stops you, it doesnt mean that you can continue doing it."
In the drama, this quote referred to the bullying when the classmates finally got fed-up with this girl for bullying people. Of course it can apply in many other things as well. Quoting this phrase for my beloved friend who.. err, suffered in a similar case.
To that beloved friend: Dun worry about it too much yarh! I think she ownself knows what she's doing is not right, but precisely because no one tells her about it, she thinks its alright and keeps on repeating the same thing. But of course friends sometimes cant bear to tell her. But remember you're not alone =) Many other people probably share the same view as you too. And i probably shouldnt say "dun think about it and you'll forget it" since its very likely that the same event happens again. BUT DUN WORRY YOU HAVE ME!! SMILE~
The next drama, "Tsubasa no Oreta Tenshitachi" (Angels with Fallen Wings)

Lastly theres "14 sai no haha" (14 year old mother).
