When the only bond between close friends is attachment, then even a minor issue may cause one's projections to change. As soon as our projections change, the attachment disappears, because that attachment was based solely on projection and expectation. It is possible to have compassion without attachment, and similarly, to have anger without hatred.
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.
Only be admonished by what you already see, not to strike leagues of friendship with cheap persons, where no friendship can be. Our impatience betrays us into rash and foolish alliances which no God attends.
