Life presents us with things that pass by once, but also with elements that come back. Words, for example. Friends.
And every time we see these returning elements, they remind us of something from the past. But they also tell us something new.
Perhaps you've seen this remix of Robin Williams by MelodySheep. Perhaps you've seen the films that occur in it. Heard those words before. Then give them new life by listening to them again. Allow them to cause new wrinkles on the surface of your mind. Or just enjoy it : ).
