The same happens in other human relationships: a man goes from one woman to another, goes on changing. People think he is a great lover; he is not a lover at all. He is avoiding, he is trying to avoid any deep involvement because with deep involvement problems have to be faced, and much pain has to be gone through. So one simply plays safe; one makes it a point never to go too deeply into somebody. If you go too deep you may not be able to come back easily. And if you go deeply into somebody, somebody else will go deeply into you also; it is always proportionate. If I go very deep in you the only way is to allow you also to go that deep in me. It is a give and take, it is a sharing. Then one may get entangled too much, and it will be difficult to escape and the pain may be much. So people learn how to play safe: just let surfaces meet — hit-and-run love affairs. Before you are caught, run.
