There are a few different ways he expresses it. Sometimes I piss him off enough to yell at me a little. But the good thing is I know with him that when I make him mad, no matter how mad he gets, he still cares and will be there for me. He expresses it much like a parent would towards a child who has done something wrong and something that the child has been told over and over again not to do. But in the end he always lets me know everything is okay. And him expressing it to me actually helps because I know he still cares no matter what I do and isnt going to leave me just so I screw up. And sometimes I think I make him mad on purpose just to get that feeling.
