person A: My wife is due next month with our first kid! I feel prepared in becoming a responsible father!
person B: Congratulation!  It is really smart to be as prepared as possible!  This baby will change your world!
person A: That's what everyone has been telling me and I bet it will.  I will think twice about all of my actions to make sure I'm responsible.
person B: That is good.  It will make you quite happy.  I couldn't imagine life without my kid now!
