One of the best books I've ever read on communication is 'Why My Horse Doesn't Listen - Learn to communicate effectively' by Vivek Mehrotra.
The word 'horse' stands for - as per Mr. Vivek-
H: communicating at home
O: communicating at office
R: communicating with relatives
S: communicating with seniors, subordinates & spouse
E: communicating with the external world
It is a great book I recommend everbody to read.
