Having A Drunk Father All Your Life

It's not easy dealing with the fact that all your dad does is drink. You would think that he would care enough to quit drinking and actually spend time with his kids. I mean it's not like he sees us all the time and his time with us is spent drinking. We are always last and we know it's not our fault but we got used to this. I don't understand why he is like this. I just wish he could see how his drinking has been affecting us for the past I don't know how many years. It probably won't change anytime soon. I don't expect him to change but I just want him to spend more time taking care of us and not worried about drinking everyday.
