Again . in Dalin

I 'm here in Dalin again, with my mother in the hospital to "enojoy" these 4-day-vacation.
after the chemical healing last month, my mom was transferred to "peaceful room" and stopped to beat against cancer. that is to say: we give up.
the ture is : bacterias of cancer have been occupied 90% of her liverpool. The chemical method we did before failed.
Now she become a little slower react and a little memory lost. besides, a weaker body, even need our hand to carry her for walk.
There is only one thing that made me feel better : she talks, thinks like a child, smile so happier than before.
Should I be happy or sad? to laugh or cry?
people always cannot realize "how to live happily" until they are dying.

the same situation could be happened to me in the future..
now I can only do what I can do to all of my family. To be with them during this limited time.
