What Would You Do?

A close friend died at age 60 of heart failure. You were her only friend for over ten years. You took care of her when she was ill and also brought to the Doctors. You treated her like she was your own sister. You knew she was a widow but you were her only visitor. You called for the ambulance the day she complained she had chest pain and she died a few hours later at the hospital. To your amazement you find out she had a son when he arrived at her funeral late and then he left early. He  had nothing to do with her the whole time you knew her. He bragged to you that he went away to college and never came back. He became a big Hollywood success and was too busy with being an agent for the stars he didn't even come home for his father's funeral.   A few days later you received a copy of her will registered mail from her lawyer that said she left her home to her son but her  two million dollars of stocks went  to you. You were shocked because your neighborhood was very modest and the homes went for not much more than $150,000.  You had no idea she was a millionaire. The next day you got a call from her son demanding you split the stocks with him. You call her lawyer back and he says the son has no case as he was left the house in the will and your friend was in sound mind when she made the will. What would you do?
