The principal : Hello dears.
Norah : We are not deers...
Me thinking : She is telling dears not deers.
Principal : Norah!
Norah becomes shocked when she told her name loudly.She was angry too,but a little sad at the same time.She was thinking something.The principal was going to burst because of too much anger at a time!
Still children aren't listening.They are seeing what she does,kinda (kind of) waiting for her to start what she wants to do that is make the special announcement she is talking about.
