It's so easy to fall in love with you.

The words hang in the air, heavy but light. Her heart beats, her breath catches, and the wheels in her mind turn even faster, the what-might-have-beens and what-could-have-beens thundering like the waterfalls that they were.

She smiles the next moment, and understands it for what it was. But a song in her heart trills, a happy song that lingers on.
