When following in the car behind Grandma and Aunt Em...
LM: Daddy, let's pass Grandma.
Daddy: We can't. She is leading us to where we are going.
LM: You don't know where you are going???
Daddy: No, Grandma is showing me.
LM: Why don't you use your GPS?
Daddy: I don't have my GPS.
LM: You should bring your GPS next time.
