Sixty degrees Fahrenheit is a temperature entirely too low for the interior of a family home. The only reason I can think of that a home might remain at that temperature for an entire week would be in anticipation of an upcoming heat wave that would surely have the resident family grateful for a pre-frozen house.
If, however, no such wave of heat should make it's appearance, the inhabitants of that house may possibly decide that, while it was fun for a while*, those ice tipped noses and toes and stiff fingers and lips are ready for a bit of a thaw.
The heater comes on after church on Sunday, and the movement of our extremities (assuming there's been no permanent damage), with it.
Current outside temperature: 46 degrees (at 3pm). What's your weather doing to you?
*Or they may possibly have hated every single second of it.
