A Cindy Quickie

Yesterday on the way to my mom's house to celebrate her birthday, I realized that I left her gift on the counter at home.   We were too close to her house to turn around, so I decided I would just take her the gift today. Cindy was skeptical of that plan and said, "I think Grandma is gonna make you go home and get it."  (She obviously knows my mom well.)  I replied, "No, she won't. Besides, she didn't really even want me to buy her a present anyway."  Cindy was really confused at that answer and said, "That doesn't make any sense.  What kind of a person would not want someone to buy them a present?"  Yeah, Grandma! What kind of a person are you??
