From Story of a Soul by St. Therese of Lisieux:

Speaking of that Blessed Mother, I must tell you of one of my
simple ways. Sometimes I find myself saying to her: “Dearest
Mother, it seems to me that I am happier than you. I have you for my Mother, and you have no Blessed Virgin to love. . . . It is
true, you are the Mother of Jesus, but you have given Him to me; and He, from the Cross, has given you to be our Mother–thus we are richer than you! Long ago, in your humility, you wished to become the little handmaid of the Mother of God; and I–poor little creature–am not your handmaid but your child! You are the Mother of Jesus, and you are also _mine!”_
