Lock and Key, Lost at Sea

My heart is a lock Your love is the key I wonder if you understand How much you mean to me Behind closed eyes like I do I often sit and ponder How much I mean to you There is none other that could ever Make me feel how I do when we're together My mind is gone Lost at sea How foolish I was To think together we'd be It's now time that pay is due I've given you everything But still I get no love from you My heart must remain hidden forever Never to be found liked buried treasure
