Kai & Gerda (The Snow Queen)

"Cutting winds were raging around her, but she offered up a prayer and the winds sank down as if they were going to sleep; and she went on till she came to the large empty hall, and caught sight of Kay; she knew him directly; she flew to him and threw her arms round his neck, and held him fast...

But he sat quite still, stiff and cold.

Then little Gerda wept hot tears, which fell on his breast, and penetrated into his heart, and thawed the lump of ice, and washed away the little piece of glass which had stuck there...

Then Kay burst into tears, and he wept so that the splinter of glass swam out of his eye."

-The Snow Queen, Hans Christian Andersen
