If we change in different directions, then we don't have any future anyway, do we? I think it's possible for two people to change together, to grow together and enrich instead of diminish each other. The sum of one and one, if they're the right ones, can be infinity! But so often one person drags the other down; one person wants to go up like a balloon and the other's a dead weight. I've always wondered what it would be like if both people, if a woman and a man both wanted to go up like balloons!
