Leave Off At Seven

Three sisters all bore witness
To horrors after recess
I sent them down the river
To offer pleasant shivers

I would advise you to get off at seven
But it's too late now
That the times are changing
I could assist
Keep you from growing older
Remain the same with no weight on your shoulders

My self has softly vanished
My reputation tarnished
There's logic in this madness
Extinct and prone to perish
