The door was shut, as doors should be …

The door was shut, as doors should be,
 Before you went to bed last night;
Yet Jack Frost has got in, you see,
 And left your window silver white.

He must have waited till you slept;
 And not a single word he spoke,
But pencilled o’er the panes and crept
 Away again before you woke…
Gabriel Setoun, Jack Frost
