Show Me You Are My Son!

One day a sinner said to the Blessed Virgin, "Show me you are my mother." And she answered, "And you, show me you are my son." And to another one who also called her, addressing her as "Mother of Mercy", she said, "You sinners, when you want my help, you call me Mother of Mercy, but you never stop turning me into a mother of misery and pain by your sins."
