The 2017 Australian Open

The 2017 Australian Open took place January 16 – 29.  In the women’s final, Serena Williams and her sister Venus Williams competed against each other.  Serena won the match with a score of 6-4, 6-4.  I am wondering if they fight at home after they compete.  I am noticing that this was Serena’s 7th Australian Open title.  That is a lot of tennis!  I also think that it would be fun to play against your sister, but it must also be really hard.  They are sisters who love each other so it must be hard to try to beat each other.  However, it must be fun to hang out together a lot and spend some time together.  I wonder how they feel.  How would you feel about competing against your family member?
