Visit to a breastcancer sister

My boss is leaving for London tomorrow to visit her sister with breastcancer. I met her many times since she loves to visit Netherlands 2-3 times a year. Its amazing that she can make herself driving 6-7 hours from London to Netherlands considering she's really ill. I remember 2 years ago when she was confined in the hospital and the doctor told her that she cant live anymore , that her life will be over anytime that week yet she asked the doctor to do their best just to make her better. And yes, its always a success everytime new experiments/medications they gave for her. I can't imagine that was 2 years ago and until now,she is alive and still kicking though her sister/s always say that she will never get better. But i believe she still have more months or even years to live knowing that she's a person with strong determination and a person with good positive outlook in life...
