The Sea Shell

I have hidden inside a sea shell but forgotten in which. Now daily I dive, filtering the sea through my fingers, to find myself. Sometimes I think a giant fish has swallowed me. Looking for it everywhere I want to make sure it will get me completely. The sea-bed attracts me, and I’m repelled by millions of sea shells that all look alike. Help, I am one of them. If only I knew, which. How often I’ve gone straight up to one of them, saying: That’s me. Only, when I prised it open it was empty.
