['When I think about happiness, the first thing that comes to mind is the overwhelming sense of bliss when my daughter was born.', "Aww, that's a nice story. I'm glad you have that to carry with you.", 'Thanks! What is a joyful moment in your life?']
I'm thinking of a time that a party was thrown for me as a surprise. All those people getting together was really fun.
I was overwhelmed with happiness the day my daughter was born.
