Here is...

Here is your smile
to open
talk.

Here is your walk
to open
hand.

Here is your face
to open
age.

Here is your age
to open
organ.

Here is your organ
to open
music.

Here is your music
to open
mood.

Here is your mood
to open
fun.

Here is your fun
to open
a gate.

Here is your key
where can I have mine.
