Leave the card and continue what you are doing
From Create Your Own Story
A few days later you come home to find your mom in the kitchen. She hears you come in and she summons you to talk to her. You walk over and she starts asking you a million questions, how your day was, what you want for dinner, and finally she hands you the card that the man left and says, " You should really call him. He is really interested to talk to you." How do you respond?
