Theresa how much one can see see at night depends on the lighting inside and outside the house and the window covering. Some houses get moon light when it is full or street lighting, although if there are light blocking window coverings then such ambient lighting is minimized. Outside lighting on a porch might illuminate the interior of the house. In a bedroom alarm clocks can put out a lot of light or very little. Some people have night lights or leave a light on somewhere. Unless you have a power outage you probably don't realize how much artificial light there is in your house.

So what you can see in your house has no relevance to any other relesidence.

I find it unbelievable that Mac did not turn on the Lights in the girls rooms. The house should have been lit up like a Christmas tree. A doctor who checks for wounds in the dark? I don't buy it.
