What is the loveliest thing a child has ever said to you?

I think who have kids, everyday a lovely thing happens. I remember, one day my son said, "Mamma, are you sad? I know you are missing nani," and then he added, "Do not be sad, I am there with you and just imagine me to be nani and you will feel better." My mother has passed away and he thinks her to have become a star so he tried to console me. And that was the sweetest thing that any kid has done to me.
