Love doesn't just sit there, like a stone; it has to be made, like bread, remade all the time, made new.

This quote is expressing that love is not something that automatically exists and stays the same; it is something that must be actively cultivated and nurtured. Just like bread must be made every day, so too must love be made and kept fresh. This means that it is important for people in relationships to take time to recognize and appreciate their love for one another and to show kindness and affection.
