What am I? Chopped Liver?

Last night, we had our friends, Ligaya and Phil over for dinner. At first Noah was really shy around them, but by the end of the night he really warmed up. He even asked Phil to read him a story.

Noah went to bed before they left and this morning after he woke up he started shouting, "Phil! Phil! Come see my airplane!" I went into to his room and said, "Buddy, Phil went home after you went to bed." Noah looked crestfallen. "But...but...he's my rockstar!"
