Friendship (n.) may be defined as a complete accord on all subjects human and divine, joined with mutual goodwill and affection.
Friendship (n.) is, wisdom alone excepted, the best thing the immortal gods have given to man.

Friendship (n.) has one rule above all: neither ask nor consent to do what is wrong.
