Where and When Lyrics

The snow was falling down like pieces of the sky last Friday night
I was outside on the street and she was inside to the beat
Next thing I know she's watching me write to her in the snow:
"Let's go"

She got up so close the condensation changed her to a ghost
She appeared again, as she wrote on the glass
"Well, it depends... where and when?"

Where and when?
Where and when?
Where and when?
