"Swim Lesson is Over"

I signed Noa up for swim lessons during the summer.  The first day she cried the entire time but the instructor, Melanie, said it was normal.  On the second day, Noa started crying as soon as we pulled up to Melanie's house... I knew it didn't look good.  Noa screamed and cried until she puked in the pool and Melanie, said "the lesson is over."  I was pissed off.  I was not pissed off at Melanie, I was pissed at Noa because normally she cries when she has to get out of the pool!
