Why Did It Not Stop?

When I saw the sun
It was setting into the horizon.
I looked at a bird
It was going away from me.
I watched a speeding car
It vanished in no time.
I heard the wind whistle
But it calmed down.
I listened to a child laughing
The voice turned dead.
I felt a soft hand in my hair
It shrugged away quickly.
A tear rolled on my cheek
It dried away and I didn’t weep.
I heard a sweet song
It ceased to sing.
I cherished a dream
It was all blown away.
I wrote a poem
It stopped rhyming.
I nurtured a plant
It stopped growing.
I held a hand
I stopped feeling.
I saw a face
I stopped seeing.
I fell in love
Why did my heart not stop beating?
