Alarm at 4:00am?

 While we were staying with the Prince kids, I was awakened one morning at 4:00am.  I woke Ken up and we got up to investigate.  
Sure enough, Alexa was sounding a loud alarm from William's room.  We told her to shut up and she did.  William kind of rolled over and went back to sleep.  We were just settled back in when she sounded again.  We went back in his room and she was screaming again.  This time Ken climbed up to where she was and, shall we say, disabled her.

The next morning we asked William why he had set an alarm.  At first he wouldn't tell us but later admitted he had set the alarms to get up and practice basketball.  At 4:00am?  It was black dark.  Funny little dude.
