Headings should read...
INT. SITTING ROOM - DAY
Overall, easy to understand and emotional so well done. I did a short story a while back called Pink Primate about a girl with an imaginary friend but it was more of the horror genre. The girl's father doesn't like her having an imaginary friend (pink gorilla in a tu-tu named Betsy). Years later he discovers it's stalking him at the school he works at. Might revisit it in the future and flesh it out more.
