BD9 recently got an old, discarded iphone that has been through several members of our family and was dropped, had the screen cracked, etc. She basically uses it to play games and surf the Internet (in our house), but she recently found an app that lets you text and email for free.

So she is setting this up and she's telling me about all the people she texted, and SD19 is one of them. My first reaction was to tell her not to text SD19, but BD9 wanted to know why. "She's my sister." Which is funny because that evening DH told BD9 to be nice to BD6 because "she's the only sister you'll ever have." Even he doesn't "really" consider SD19 to be their sister.

Let me backtrack and say there has NEVER been a time SD19 acted like a sister to BDs 9 and 6. When she was younger she tried everything in power to hurt them and sometimes succeeded. When she got a bit older she ignored them completely and refused to come to their activities. When she left our house, she NEVER and I mean not even once in the intervening five years ever called to talk to them. She doesn't acknowledge their birthdays, I'm not even sure she knows when they are. She never played with them, took an interest in them, nothing. In fact, she liked to badmouth me in front of them to try to get them loyal to her over me. It didn't work.

So now in this electronic age, I'm afraid there's no keeping BDs away from SD19's evil influence. If they get a Facebook page, they'll want to add her. They'll want to have the freedom to call or text her (she has yet to respond to BD9's text by the way).

What do I do? I know SD19 is technically their half sister, but I'd just as soon keep them separated until SD19 grows up and gets to be a decent person, which at this time she shows no intentions of doing.
