<human>: Can you summarize the given text in a few sentences?

I'm married with a small child. Tomorrow I have a call with my father to bury the hatchet and end a 1-year estrangement. Neither of us is a terrific communicator; I'd appreciate tips on making this a successful call.

My goal for the call is just to reestablish a functional relationship with my parents: holidays, news-sharing, and occasional visits.

History: about a year ago my parents made controversial decisions with an estate; without getting into the details, in the interest of money they decided to disregard some informal bequests and made some very unsentimental decisions that were devastating to some family friends. I felt a duty to rise to the defense of the family friends, and it was a very ugly year -- I haven't seen my parents in a year at this point. We were unable to change the outcome, and we've "lost the war" at this point -- the family friends who'd been wronged have moved on, and the extended family who'd initially sided with me have capitulated. The last six months has been little little more than an emotionally destructive back-and-forth with my father, without much purpose.

My father is old and unhealthy and I have a young child who misses her grandparents; the dispute cost us a lot of time we won't get back. I left my father a quick voicemail on Friday indicating that I was no longer arguing. He left me a voicemail today that he wanted to discuss reuniting our families.

I'll need to call him back and have a discussion. I still think what he did was reprehensible; I don't think he expects an apology. I just want to re-establish a working relationship that lets my child spend some time with his grandparents and relieves the tension from my extended family.

I'd appreciate advice on how to approach this conversation.
