This is what George MacDonald had to say on the subject of light (from The Light Princess)

"It is a good thing to be light-hearted, I am sure, . . . ."

"It is a bad thing to be light-headed," answered the queen, looking
with prophetic soul far into the future.

"'Tis a good thing to be light-handed," said the king.

"'Tis a bad thing to be light-fingered," answered the queen.

"'Tis a good thing to be light-footed," said the
king.

"'Tis a bad thing--" began the queen; but the king interrupted her.

"In fact," said he, with the tone of one who concludes an argument
in which he has had only imaginary opponents, and in which,
therefore, he has come off triumphant--"in fact, it is a good thing
altogether to be light-bodied."

"But it is a bad thing altogether to be light- minded," retorted
the queen, who was beginning to lose her temper.

This last answer quite discomfited his Majesty, who turned on his
heel, and betook himself to his counting-house again. But he was
not half-way towards it, when the voice of his queen overtook him.

"And it's a bad thing to be light-haired," screamed she, determined
to have more last words, now that her spirit was roused.

The queen's hair was black as night; and the king's had been, and
his daughter's was, golden as morning. But it was not this
reflection on his hair that arrested him; it was the double use of
the word light. For the king hated all witticisms, and punning
especially. And besides, he could not tell whether the queen meant
light-haired or light-heired; for why might she not aspirate her
vowels when she was exasperated herself?
