Our second story window just fell out the window. Yes, you read that right. Apparently, it's designed to tilt inwards so you can clean the outside, but it wasn't installed correctly (which explains why it wouldn't stay in position all these years). Today, while my mother was trying to clean it open it, it fell out entirely, landing on the clay two stories below. Surprisingly, it didn't break, so I figured out how it went in and put it back, properly. Now it stays in place if you raise or lower it!
