I think she is scared and kind of shy because she does not have much experience about going to school she also do not have any true friends and only knows 3 people in the school so far Jack, Julian and Charlotte. Julian was not really nice to Aggie, he ask Aggie what was with his face  which I thought was not really nice because he thought he was probably in a fire. Julian was also standing in front of him every time he was trying to look inside. I also think he has the laugh and sad feeling because he is sad but happy that he hasn’t  started school and probably has mix feelings.
