To steal a heart

Sweat beading on my brow  
fingers and back cramp in agony  
concentrate  
feel the...
'click'  
*deep sigh*  
as another tumbler falls into place  
why...  
did I attempt this lock?  
so much harder  
than anything I've tried before  
oh, but the riches held within  
is it greed  
or ego  
to test myself this way  
and finally  
open your heart  
but then you give me the key  
as I look with wonder  
into your eyes  
to find a thief has stolen my soul  
"what shall we steal next my love"
