You don't know it

Source

 
You don't know it, but your presence
fills every dark corner with joy,
your smile lights my way
and your voice is the music that intoxicates me.
You don't know it, but you are the owner
of my heart and my thoughts,
every heartbeat, every dream, every desire
has your name engraved in its centre.
You don't know it, but you are my inspiration,
my muse, my reason for being,
and even if you never know it,
you dwell in every verse I write.
