Reason?

Moist eyes seem so lively today,
full of dreams, as if something has returned..
The noise of birds seem musical,
the flowers seem blooming,
moments ago who were so dull..
The dead touch feels so full of life,
the screams of children,
a beautiful song,
what happened suddenly?
Was it your return,
which brought me back to life?
Or was I too busy
to understand the love for life?
