On friendship

The worst solitude is to be destitute of sincere friendship.

AND

Sometimes the measure of friendship isn't your ability to not harm but your capacity to forgive the things done to you and ask forgiveness for your own mistakes.

AND

Friendship with oneself is all important, because without it one cannot be friends with anyone else in the world.

AND

'Tis the privilege of friendship to talk nonsense, and have her nonsense respected.
