Post id, frumenti quum alibi messis maxima'st Tribus tantis illi minus reddit, quam obseveris. Heu! istic oportet obseri mores malos, Si in obserendo possint interfieri.
— Besides that, when elsewhere the harvest of wheat is most abundant, there it comes up less by one-fourth than what you have sowed. There, methinks, it were a proper place for men to sow their wild oats, where they would not spring up.
— Plautus, Trinummus, IV. 4. 128.
Ingratus est, qui beneficium accepisse se negat, quod accepit: ingratus est, qui dissimulat; ingratus, qui non reddit; ingratissimus omnium, qui oblitus est.
— He is ungrateful who denies that he has received a kindness which has been bestowed upon him; he is ungrateful who conceals it; he is ungrateful who makes no return for it; most ungrateful of all is he who forgets it.
— Seneca, De Beneficiis, III. 1.
