dad's dream

As my friends knew that my dad was from Mainland China when he was out of his teens.At that age everyone who was from China had their own stories.My dad is not an exception.

At the beginning the government only permitted they could mail letters to their family of China.The address of the first letter was wrong.Unfortunately my grandmother had passed away before the second letter was arrived.She had not known any message of her son no matter live or dead.According to the dad's older brother said my grandma often whispered my dad's name before died on her bed at her ninety-five.

A week ago dad told us he had dreamed of his mother.In the dream he leaned against the wall. There was a sound behind him and he knew it's her mother's voice who was talking to someone about her house was needed to repaired.He turned around to see her mother.At this time he is pouting with a disappointed look and saying his mother had not recognized him at all.
Maybe you took a mistake she was not your mother.You haven't seen her for more forty years.I tried to comfort him.
It's the young look of her mother in the dream, he said.It's the only one image of his mother he has.
OMG! No wounder his mother could not recognized him. He is eighty-two years old now. He wasn't the young man his mother remembered.
They couldn't meet each other even in the dream.
How come?
