Singing in the mornin'

I love the sound of happy boys getting ready for school in the morning.  As I type this quick post, they are singing in the upstairs bathroom while brushing their teeth.  So happy!  Wait a minute, if they are singing, they can't be brushing their teeth.  And now, there are banging sounds, and, what's that?  Wrestling!?  We're going to be late for school!  Stop, boys!  Get down here this instant!  And in a matter of seconds, our morning has gone from happy to frantic.
