One Roll

Two bathrooms.  One roll.
I hold in my hand the last remaining roll in the house.
I considered hiding it and then I started thinking, why don't we have some sort of alarm for this situation?

I mean, when you get down to three rolls in a two bathroom house a buzzer should be sounding all over the house and the only way to stop it is to put more paper in the bathrooms.

 I chose not to hide this last roll.  The possible consequences seemed too severe.
