    It was hot and yet, such a beautiful day. My parents and I picked up my grandmother from the nursing home. We used to go there regularly but the last time I visited my grandmother, she seemed to forget where she was and how to breathe on the massage (按摩) table—it scared me so I thought perhaps it was better to transfer her to a clinic that day.

She had been getting weaker and having aches from sitting in a wheel chair all day, so I called Wang Tao who runs a Chinese massage clinic with his wife and daughter out of their home and told him my concerns wasn't even sure whether my grandmother would be strong enough to get up the stairs or get onto the table.

''We can help her make it'', Wang Tao said. And, we did. Sure there were struggles and funny moments. For example, my grandmother wondered who was the man working on her back, Wang Tao had massaged her over the years at least 20 times. They used to laugh and talk together in Chinese but my grandmother didn't remember. Wang Tao was shocked that my grandmother seemed to have forgotten he is a Chinese man, but he still patiently tried to refresh her memory.

My grandmother was born in California, but her parents who were born in China only spoke Chinese, so Chinese was her first language but English is spoken all around her. Still, our family all felt grateful and happy to hear my grandmother start talking to Wang Tao in Chinese again. It was like the dust just needed clearing. We all laughed a happy laugh. When the session was over, my grandmother took Wang Tao's hand and thanked him for helping her. We ended our day with a Chinese dinner of course-one that ended with my grandmother saying to the massager: please come here and I have to shake your hand. ''Thank you for what you have done. '' she said joyfully as she held this stranger's hand. And then she turned to me, ''Thank you, my grandson. ''
