Harry and I had the following conversation this afternoon:
H: "Sofia kissed me on the playground today."
Me: "She did?"
H: "Yes. I do not want her to kiss me on the playground. She telled me I am her boyfriend."
Me: "Wow. Is she your girlfriend?"
H: "SHE IS NOT MY GIRLFRIEND."
Me: "Do you know what a girlfriend is?"
H: "No. What is it?"
Me: "Well, if Sofia was your very favorite girl, then she could be your girlfriend."
H: "She is not my favorite girl. I like everybody the same."
