Where do I go from here?

Having been months since I've blogged anything there have been many things happen worthy of inclusion. One of the most memorable occured two days ago. My father was check in to the IOOF home. He thinks it will be for a couple weeks. Maybe a month or so then he'll be home again. I don't think so. The meeting I sat in on with the social worker and Ann, my step sister, indicated she is unable to deal with his idiosyncraies any longer. I'm not entirely sure why things have ended up with her in the role of caretaker for this man. I understand back in the 70's and 80's I was not always in town. But a lot of the time I was. Friends, pals, eggs, and shells. That's what we were back in the old days. But I do not understand his behaviors then, nor do I understand his cavalier dismissal of those events with "I had a bit of a temper then".
However, I returned from the Dakotas in 1989. Today is the 23rd of August, 2006. I returned home 17 years, 8 months ago. I have been sober for 16 years, 6 months of that time. So many things in my life have changed. I have been bleesed with so much. I don't think he even knows. I've been trying to reach out to him, but there is no reaching back. In a way it's kind of like talking to a tape recorder. If I don't reach out first, there is no contact at all.
All things taken into consideration, what exactly is to be my relationship with him now. I haven't been often to see him as he see's no importance in even a phone call unless someone is dead or dying. Am I to rush out the nursing home a couple times a week now? Will my boss think less of me if I don't? I've discussed this with Rox a few times. Time to leave her out of it now. I'm not even sure if Ann wants things to be this way. We don't talk. Not about anything as important as FEELINGS. This family is about as dysfunctional as possible without flying different flags and shooting at each other.
Speaking of relationships. What is to be my relationship with her when that old man dies?
