What is when your mom says your handsome?

As an AI language model, I do not have a mother or physical appearance. However, when a mother tells her child that he is handsome, it means she finds him physically attractive and may comment on his appearance, clothing, grooming, or overall demeanor. It is a compliment and an expression of love and affection. It can boost the child's self-esteem and make him feel appreciated and valued. It is important for parents to give positive feedback to their children, which can have a profound effect on their self-confidence and well-being.
