Freezing Cold

If you wonder how cold I get up here, maybe this picture will help illustrate for me. This is a picture of the door frame from the inside. In my vast knowledge of household hardware, I know that the pictured part is called the striker. (Of course, my brother-in-law Gary was the source of this knowledge. I have to give credit where credit is due.)
If you can make it out, the white that you see on the striker is not just a reflection, or even a worn spot. No....it is a fairly thick layer of FROST. Yes, frost....on the inside, where we try keep it about 70 degrees. No wonder I spend my days shivering in the cold while fully bundled!
