I know, too, that you are not a hugs type person, but I send them anyway.

Your sister threw out the baby with the bathwater, as we say in the south. She should have given you two a chance to know each other, and kept the good things in her previous life (you) and left behind the bad. Whereas a child not your own is not something you can take with you, she could have made the attempt to stay in contact, or at least have done so once you were an adult. Her loss, and I regret that it is one that causes you hurt.

Just my $0.02 worth.
