In Nick Hornby's "Funny Girl," the concept of love is intricately tied to the idea of courage. It suggests that true love requires vulnerability and the bravery to express feelings openly. Without this bravery, an individual undermines their arguments for love and risks losing the connection they desire.

The quote emphasizes that a person who is afraid to openly declare their love is not deserving of that love in return. This perspective challenges individuals to confront their fears and communicate honestly, highlighting that love should be about both expression and accountability in relationships.
