<human>: Can you succinctly summarize the text in 1-3 sentences?

My fathers side of the family hates eachother due to drugs, prison and general pettiness. He doesn't talk to his siblings his mother because they are always fighting about something. That being said, I'm more concerned about my generation of the family. 

I grew up in a divorced household so I never really think about reaching out to my siblings or parents because I'm used to them not being around, but my sister recently had her first child and called me crying that she missed out on having "real family" (she has a different mother and lives far away). She said she was going to call our brother and dad to tell them the good news, but aparently never did. My brother is upset with her and I feel like my father doesn't want anything to do with her.

I love my dad, but I'm tired of this family drama. I want to start a dialogue between my brother and sister to bring us together so we don't end up as bitter as the rest of our family, but I don't know where to start. Any ideas?
<bot>: I want to make sure my brother and sister don't end up hating eachother like our aunts and uncles. Help?
