Samantha on a roll

Samantha gets some roller skates, but her mother cautions her not to put them on until her mom has time to go with Samantha. Of course, Samantha does not listen. She puts the skates on anyway and all too soon she is careening down an enormous hill, helplessly grabbing for anything she can reach to try to slow her down. But to no avail.

“Slow at first, she glides downhill.
Quickly then,
And quicker still,
Till the scenery's blurring past—
Sammy's going VERY fast!

(Meanwhile Mama, changing John,
Doesn't realize Sammy's gone.)”
