semper tibi confide
i always trust you

ab hoc die bonus discipulus ero, magister: numquam in ludo dormiam, semper tibi parebo, bene computabo et pulchre scribam! quid? bonus discipulus eris? id fieri non potest! cras rursus in ludo dormies, male computabis, foede scribes, nec mihi parebis!
from this day i will be a good disciple and teacher: i will never sleep in school, i will always obey you, i will compute well and write beautifully! what? will you be a good student? that's not possible! to-morrow you will sleep again in the game, you'll count badly, you will write foully, and you will not obey me!
