We don't. We got along as kids until she was strong enough to physically overpower me. I moved out when she was still in high school. We didn't have much contact for years. She was in and out of various housing situations. She would get herself in trouble in various amounts of seriousness and my parents would always bail her out. They paid thousands to support her and keep her out of legal troubles.

Then she disappeared for years. We didn't know if she was alive or dead. My father died and I saw her briefly. Then again gone for years. She finally contacts my mother to say "hey you're a grandmother!" Oh and that her baby's father was a much older man with adult children who also sold crack. He also convinced her to visit my mother and disappeared while she was here. That was years ago. My sister still lives with my mother, doesn't work, doesn't contribute to society and we have no contact with each other.

I don't like her as a person. We wouldn't be friends if we met on the street. She's has a carbon copy attitude of my narcissistic mother. They didn't get along well for the first several years they lived together until they had a common enemy: me.

I don't talk to her at all and I'm fine with it.
