Class and relationships

I am taking a required Sociology class thru correspondence this summer and it is called The Changing American Family. Basically it's all about relationships, marriages, having children and life until death. Well, there is a communication section in the book so I went over some of the things w/ Don. To me it seemed like in one ear and out the other. However, when I got home from work today we were having a discussion and apparently I got a little attitude. Then Don proceeded to tell me I wasn't "communicating" with him! I should have known that was gonna bite me in the ass...
