"Is 'Our Song, Her Now' a real song?"

I drove past your apartment today.
The curtains were shut before midday...
Didn't you use to love the morning sunshine?
So why are you sitting in a pitch-black room?
The lilacs we planted together-
they're dead now.
Does their smell bother you too?
Is that why you won't water them?
It's 3 in the afternoon.
I was hoping you'd step out, like you used to.
What about your bittersweet coffee?
But then I saw her-
a girl opening the blinds,
wearing your blue sweatshirt.
Do you remember?
I knit that for you.
It kept you warm,
while you kept me warm, too.
And you used to joke
that I fit you better than any clothes ever could.
So as the raindrops poured from the sky,
I smiled at the dark clouds-
already knowing
I won't get any sleep tonight.
Not because I'm scared of the storm,
but because it'll remind me of you.
You came out and had coffee together,
dancing to the soft music, I can't hear.
It made me wonder
how easily people leave
and how quickly they replace them-
hiding their shadows in dark places,
bleaching their footprints
until they're gone.
Isn't it kind of ironic?
That I sit here in what we call our car,
parked outside what we called our home,
crying over our song,
only to realize...
this song probably reminds you of her now...
