LOVE IN THE FAMILY

"SON: Daddy, I fell in love and want to date this awesome girl! FATHER : That's great son. Who is she? SON : It's Sandra, the neighbor's daughter FATHER : Ohhh! I wish you hadn't said that. I have to tell you something son, but you must promise not to tell your mother. Sandra is actually your sister. The boy naturally bummed out, but a couple of months later SON: Daddy, I fell in love again and she is even hotter! FATHER: That's great son. Who is she? SON: It's Angela, the other neighbor's daughter. FATHER: Ohhhh! I wish you hadn't said that. Angela is also your sister. This went on couple of times and the son was so mad, he went straight to his mother: SON: Mum I am so mad at dad! I fell in love with six girls but, I can't date any of them because daddy is their father!The mother hugs him affectionately MOTHER: My love, you can date whoever you want. Don't listen to him. He isn't your father." One word for this family??
