Who Are these People Called Family?

Our biological father would suddenly appear back in our lives. When we were kids he'd drive up unannounced. "Hey kids let's go for a drive!" I was sure he was planning to kill me.

As an adult I'd get a call. "I'm going to be in Pawtucket at the side of the road would you like to meet?"

Now my sister does the same thing.

I'll spring for lunch and buy them drinks and they'll vanish again for four or 12 years. 

20 years went by before I saw my half brother. He said he wasn't allowed to see me. When our parents died he was FREE to visit. I didn't recognize him at all on the inside or the outside.
