Avoiding Interpersonal Conflicts

I myself would not choose to avoid conflicts. I like to face them head on and hope to not crash. My dad on the other hand tends to avoid conflict a lot, especially with me. I was having a conversation with him about going out of town for the weekend. I told him before I asked that I was not sure what he was going to say. I was right, I did not know what he was going to say because he did not say anything. When I asked him, he asked a few questions and then just got up and walked away. My dad used physical avoidance inorder to avoid answering my simple question, which had a simple answer of yes or no. For the both of us it is a lose, lose situation because he has to try and avoid me, while I lose because I did not get an answer. I wish that my dad would give me an answer, especially the one I want. But if it came down to it I would rather have him be accomodating, have his way because at least he would not have to try and avoid me then and I would not be in an awkward situation of not being able to give my friends an answer.
