Authors do so love to romanticize cold hands.
Saying thing like:
"He used to rub my hands to keep them warm."
"He always held my hand to keep it warm."
Those are lies.
Nobody wants to share you coldness.
No one wants you to touch them,
Not with your cold hands.
And when they get painfully cold,
And your hands are stiff and red,
No one will be there to warm you back up,
I would know.
