It is not OK in this culture to talk to friends about causes you believe in, much less to ask them to join in. It's OK to blast perfect strangers with crass messages every hour of the day, but it's a tinge embarrassing, it brings up some shyness, it seems an intrusion, it risks rejection to share real heartfelt commitments. It's easier to share our cynicism with strangers than our dreams with friends.
Life's like a movie, write your own ending Keep believing, keep pretending We've done just what we set out to do Thanks to the lovers, the dreamers, and you.
