That gift is said (to be) good, which is given, because it ought to be given, to one who (can) do no service (in return), at a (proper) place and time, and to a (proper) person. But that gift which is given with much difficulty, for a return of services, or even with an expectation of fruit, is said to be passionate. And that gift is described as dark, which is given to unfit persons, at an unfit place and time, without respect, and with contempt.
