Very Disappointed

I woke up this morning to hear the following conversation taking place in Harper's room:

Harper: "AH!"
Sky: "Harp, don't yell."
H: "AH!"
S: "Don't yell. Don't."
H: "AH!!"
S: "DON'T YELL!!!"
...
H: "AHHHHHHHHHH!!!!!!!!!!!!!!"
...
S: "Harp, I am disappointed."
H: "AHHHHHHHHHHHH!!!!!!!!!!!"
S: "I'M VERY DISAPPOINTED!"

This was followed by the sound of Sky slamming Harper's door, then Harper breaking down into sobs. Harper seemed to be very disappointed in Sky.
