God mother blues

So my best friend is 8 months pregnant, and has dubbed me the god mother. I thought she ment this as a cute title for me, just because I'm her friend right? Turns out she is serious and that's a real thing in her family. A god mother takes the baby or kid if something happens to the parents, and even helps with it. She knows I hate kids, and I tried to hint strongly I would not do that. But she refused my hints. She's smart and knows me so well, so i KNOW she got them. I will put up with her kid, but am not going to help her with it. Its not my baby! Her moms even said she was mad that i didn't want to do it. I literly know no one who does the good parent thing and need outside help!
