So windows can whistle...

This past weekend a good buddy of mine from my days in DC came to stay with me for the weekend. I've not seen him for almost 4 years but it was like I'd seen him last week. Friends like that are rare and far between and it was great to hang out again. Back to the point, Saturday night was a windy one here in the Windy City. Tonight is as well, which is what reminded me. So it seems that the windows of my apartment are so positioned that a heavy wind happens to interact with the sealing on my patio door to cause a high pitched whistle. I had the pleasure of being awakened at about 3:00 am to such a whistle- I'm sure you can imagine my happiness. I just heard it again...I'm sure this is the beginning of many a fun evening as Chicago's winter season settles in.
