Jennifert what a hilarious story! I was picturing the whole thing in my mind as I was reading. It is very funny now but I am sure it wasn't at the time! I am so glad for you that you left a window open. I hate to think what would have happened if you hadn't! It might be a good idea to hide a key outside, like someone else mentioned, just to be safe! I am so glad you are OK and not all frostbitten!
