If/Then

As long as the night
Carries to the dawn
As long as I know that the day gets reborn
I promise I'll try to not mind the dark
As long as you promise me somewhere out there there's a spark

And as long as the summer
Promises to end
As long as I know that there'll be winter again
I promise I'll try to complain a bit less 'bout this heat
As long as you promise me at some point there'll be a relief

And as long as the sun
Promises to set
As long as I know that I'll be able to rest
I promise I'll try to not mind this light
As long as you promise me I'll get some kind of sleep tonight
