Few things tend more to alienate friendship than a want of punctuality in our engagements. I have known the breach of a promise to dine or sup to break up more than one intimacy.
You are almost not free, if you are teaching a group of graduate students, to become friends with one of them. I don't mean anything erotically charged, just a friendship.
True friendship multiplies the good in life and divides its evils. Strive to have friends, for life without friends is like life on a desert island... to find one real friend in a lifetime is good fortune; to keep him is a blessing.
In the sweetness of friendship let there be laughter, and sharing of pleasures. For in the dew of little things the heart finds its morning and is refreshed.
