I don't think life offers any greater experience than the joyful sense of recognition when one finds in a new acquaintance a real friend, or when an old relationship deepens into friendship, or when one finds an old friendship intact despite the passage of years and many absences.
Go face the fire at sea, or the cholera in your friend's house, or the burglar in your own, or what danger lies in the way of duty, knowing you are guarded by the cherubim of Destiny. If you believe in Fate to your harm, believe it, at least, for your good.
First and foremost, be faithful to your superiors, keep all promises, refuse the friendship of all who are not like you; and if you have made a mistake, do not be afraid of admitting the fact and amending your ways.
