Colder Outside Than In

When it's colder outside than in
A woman's a fool to leave the door open
She may choose to not lock it
In case another soul is in the cold
Not because he likes it
But because he doesn't know
How to build a fire and keep it going
The best she can do is keep her own fire going
Willing to share the spark and anything she can
Accepting that other souls are out of her hands
