Book idea... I need help for research

I know posting this in the poetry forum wasn't smart but I figure that you guys might be able to help me out.

I'm thinking about writing a book about why people talk behind your back. I have my own personal observations that can back up my reasoning, but I need to do some more research, so I can have concrete evidence.

So if anyone knows any good books in the vein of my book topic, PM me.

bacause people are scared to tell you to their face, it makes them feel powerfull to talk behind your back because you (the victim) cant do $#%^ about it..

some people just think its fun to talk behind ones back

i hope it helped a bit?

Yeah, it helped but I need actual books that touch on this subject.

Thanks anyway.
