when u approach her the right way she is the sweetest person. very kind, very compassionate etc. even to ppl she once hated. i honestly wish i could be more like her.
She can be kind towards her friends and still be a bully.
At least for arguing over that idea itself rather than the specifics of Lena, this is very true. If you treat a bully right s/he'll often stop bullying you, as bullies are often lonely people who just want to share their own pain with others, usually coming from a damaged or broken home with this being their outlet for problems there.
How do you think I avoided being bullied growing up? They just want someone to talk to.
