Sweet nothings

Hearing such words as these, in the sweetest, tenderest voice that ever caressed a lover's senses, Basil knew not how to word all that was in his heart. . . . Side by side, forgetful of all but their recovered peace, they talked sweet nothings.

[T]he facts, to make matters worse, were made public with the usual affectionate letters that passed between them, full of sweet nothings.

It is difficult to know how accurate this portrait is, and how much of it consists of sweet nothings whispered into the author's ear by loyal retainers.
