There's a chance, a slight chance, that I may have a biological sister out there... If what I've learned is true, she is just a year younger than I. That's not unusual for adopted children. Sometimes birthparents feel such guilt that they have another child to replace the one they gave away. And if it is true, the next baby was also a girl... And her middle name is exactly the same as mine now. But I still don't even know that this is for a fact the truth.
