Jane weeps not for her dad when none is by,
Yet when one enters she begins to cry.
Not by its wish for praise is true grief shown:
He mourns indeed who mourns when he’s alone.

Cf. Plerique enim lacrimas fundunt, ut ostendant; et toties siccos oculos habent, quoties spectator defuit. Seneca, De Tranquillitate Animi 15.—“Very many shed tears merely for show; and have perfectly dry eyes when no one is looking on.”
