“No distance of place or lapse of time can lessen the friendship of those who are thoroughly persuaded of each other's worth.”

“What man can you show me who places any value on his time, who reckons the worth of each day, who understands that he is dying daily?”
Quem mihi dabis qui aliquod pretium tempori ponat, qui diem aestimet, qui intellegat se cotidie mori?

“There is no word for our kind of friendship. Two people who don't
see each other a lot, but can make each other effortlessly happy”

“The essence of true friendship is to make allowance for another's little lapses.”

“Marriage is the highest state of friendship. If happy, it lessens our cares by dividing them, at the same time that it doubles our pleasures by mutual participation.”

“The difference between friendship and love is how much you can hurt each other.”

“So they spoke, and both springing down from behind their horses
gripped each other's hands and exchanged the promise of friendship;
but Zeus the son of Kronos stole away the wits of Glaukos
who exchanged with Diomedes the son of Tydeus armour
of gold for bronze, for nine oxen's worth the worth of a hundred.”

“For friendship makes prosperity more shining and lessens adversity by dividing and sharing it.”
Nam et secundas res splendidiores facit amicitia et adversas partiens communicansque leviores.

“God, how we get our fingers in each other's clay. That's friendship, each playing the potter to see what shapes we can make of each other.”

“Love and friendship exclude each other.”
