An Unexpected Surprise

I had written about my daughters staying up late during their break.  Every day, I or someone has to shut off an alarm that Michelle has set.  She even claimed to have turned it off the other day.  I had to tell her that I had turned it off.  This morning, her alarm started its beeping.  I went back to turn it off.  To my amazed eyes, Michelle was actually getting up to turn off her own alarm.  I asked her who it was.  She said Michelle.  I told her that I did not think Michelle woke up until 10.  I later found out that she went to bed early last night.
