Best thing about summer when you're a kid is that you can play outside all day.  From the crack of dawn till the edge of dark, you can just play, play, play.  

You have no school.  The days are soooo long.  And it's warm out.

And then finally, when you do go to bed, you're so exhausted you fall asleep hard.  

Until the next day break, when the fun starts all over again.
