The other day I was talking to a child about arranging for her to come to our place after school.
Her: You have to call my mom. Do you know her phone number?
Me: Not by memory, but I have her business card at home.
Her: Is it the one with the "Come travel with me" on it?
Me: I don't know if that's the one. Does she have more than one business card?
Her: Yes....she has tons of them!
Me: Hmmm, do they all look the same?
Me: Good, then that's the one I have.
