Anchor

I am an anchor in the ocean I'm sure there's a boat above I cannot crane my neck to look Just trust me, its there It stays above me in the ocean Held firm by my grip Saltwater in my fractures Rust heavy on my skin I am an anchor in the ocean There must be a boat on this chain Why else do I sit here waiting Can metal rot amid the waves If there's no boat on the ocean And I am waiting here alone One day my boat might come back And give me purpose once again
