At 4:37 a.m. I woke up to my mind jumping from thought to thought. As I lay there trying to go back to sleep there was a loud bang in the house. It had snowed all day and was very cold so I thought a water pipe may have frozen & burst in the basement under my bed. I had unhooked the garden hoses over a month ago and insulated the area so this was really unlikely but it just shows you how a black dog seizes on any little thing and turns it to the negative. The bang was probably some part of the house settling or my dog in another part of the house knocking over something.
