Family Drama

I got a phone call from my mom the other day telling me her dad was up visiting.  Knowing my grandpa I was shocked.  She told him that there was something he needed to talk to her about in person and it could not be done over the phone.  I was thinking to myself as she was telling me what could this possibly be.  I knew he had some doctors appointments about a week earlier and wondered if maybe he had some health issues.  The only problem was with my grandpa everything was a life or death situation so you never know if it is something serious or just a cold.  My mom continued on to tell me that she had a long lost half sister.  She in 49 years old and live in Austrailia.  Apparently way back before my grandparents moved to the United States my grandpa had an affair.  Apparently the lady was also married so she just raised it with her husband.  She never told my grandpa becasue he had already immigrated to the U.S.  Apparently when the girl was about 15 she had a fight with her mom and her mother told her that her dad wasn't really her dad and threw out my grandpa's name.  I don't know how long she has been searching for my grandpa but she just found him a few weeks ago.  He did a DNA test to find out that the probability she is his daughter is 99.99%.  I guess it's a good thing my grandparents got divorced a long time ago.
