The true man in your life that is their for you. Your Dad may also be your Father but your Father may not be your Dad. Your Dad loves you, comforts you, supports you and helps you. Your Dad is someone that you should be able to respect (even if at times you don't show it).
Me: My birth Father is a man I could never respect. He was never there for me even though he could have been. The man my Mom later married was one of the nicest, most trustworthy and loving people I have ever known he is my true Dad.
