Communicating With Dad for Dummies.

Ok, give me CEOs or Directors of any company, I wouldnt have any problem communicating with them. Except for one people - MY DAD. Everytime I talk to him, there is always unnecessary tension going on. I guess after all these years, I still havent learned how to speak to him. Am I being overly sensitive? Maybe I am. and HE SHOULD KNOW BETTER. shouldn't he? I am just so disappointed with myself. Why cant I just fake it for my dad? Why cant I just do my PR thing with my DAD? Maybe I dont want to. because after all, he IS my DAD and I want to be able to be GENUINE with him. I figured the only place I can be myself is at home, with my own family. Is that too much to ask?
