When the streetlights come on and the fireflies flicker
I am walking her home making plans
With her shoes in her hands, I am watching her dance
As the hem of her dress gently kisses the grass

It suddenly rains on us
She is laughing and turns up her hands

Like autumn turns leaves 
Winter will breathe
Cold on her necks 
Snow in our paths
Wherever she goes
All that I know about us is that beautiful things never last
That's why fireflies flash

When this summertime ends, we will not part as friends
Things were promised in blood, we have sinned
Now there's tears in her eyes as she's screaming goodbyes
I run 'long side the car turning numb to the sound

I notice a chill in the air
September is creeping up fast

Like autumn turns leaves 
Winter will breathe
Cold on her necks 
Snow in our paths
Wherever she goes
All that I know about us is that beautiful things never last
That's why fireflies flash

Innocence didn't mean we're immune to these things
Let's blame the passage of time
Love and loss, truth it costs more than I can spare right now
Maybe it's simplier to lie

Like autumn turns leaves 
Winter will breathe
Cold on her necks 
Snow in our paths
Wherever she goes
All that I know about us is that beautiful things never last
That's why fireflies flash, oh
That's why fireflies flash, oh
