cute little question

Friday the kids and I headed over to my parents to visit. My dad had an appointment for Maggie, their dog, to get a rabies booster shot at the SPCA. He asked if he could take the girls with him thinking it would be fun for them to ride in Grandpa's car with Maggie. When I was telling the girls about where Grandpa was going and why, Isabel looked up and said: "Why is Maggie getting shots? Is she going to kindergarten too?"
