son finds out the reason behind his mother’s strange disappearance every christmas when he receives a letter

Doubts

As the years passed, John had become more considerate about her mother’s safety than knowing about her secret. He wished if he could talk to her about the same. He wanted to drop her off wherever she used to go. But he didn’t know how would he approach her and what he would say. He was doubtful if she would tell him the truth about her whereabouts when she had kept it a secret for several years.
