Sleep over = no sleep

I picked up Alex from a sleep over this morning.  There were about 10 boys that slept over (it was for a birthday party).

Alex said that the first thing he will do when he gets home is go to sleep.  He will sleep for 10 hours.  I said, was it an all nighter? 

He said No.  They went to bed around 4:00AM.  He said he could probably have stayed up longer, but, everyone else went to sleep.  Then, they all got up around 9:00AM and went upstairs to have breakfast.  Alex said he was having a hard time opening his eyes and keeping them open.  The sun was also a problem, shining brightly into his eyes.

I asked if everyone felt that way.  He said, yes, except one boy went to sleep at 11:00pm.  The boy went upstairs and slept because the other boys kept him awake with all of their talking.

I said, well, he must have felt pretty good this morning.  Well rested and ready to go. 

Alex said, Yea.  He was the only one.
