"First love is a kind of vaccination which saves a man from catching the complaint the second time"

In this quote, Honore de Balzac compares puppy love to a vaccination. Just as a vaccination secures an individual from getting an illness a 2nd time, first love safeguards a man from experiencing the same heartache and discomfort in future relationships. It is an effective and transformative experience that teaches a person about love, trust, and vulnerability. Through puppy love, a male discovers important lessons that can avoid him from making the same errors and falling under the exact same patterns in future relationships. It is a kind of protection that permits a male to method love with caution and wisdom.
