What is friend mean?

Today i added a girl from facebook, she quite nice and mature but i didn't mention to flirt her....
why my friends Herman and Joe keep annoying....
i didn't do anythings, i just wrote mind to intro herself and ask her which studio she learning her new jazz, that's all.....
got any problem?....
just a normal conversation to know a new friend......
but why they 2 keep annoying ?...........
1 of the comment box herman wrote "im not revenge.. im telling the public about the "TRUTH" ( act he is a good guy la)"........
I'm not a good guy?...
i didn't murder,rape or even steal before.......
a guy like him is call good guy?...
in my view, my answer will be yes, because another side of him is really a good guy ....
i trusted him so much then he answer me like this......
i was quite disappointed with him.......
but i will still friend with him...
then about Joe.....
sometimes your mouth quite busuk....
why always follow herman food step.....
people said what , u still want to add oil in it...
but still the same ....
friend always a friend........
but don't make me regret about what i trusted in u 2....
