Sounds like you got off pretty lucky... I am happy about that. Still have to hate the idea of someone forcing their way into your home like that. I hope you are able to do something with that window so it isn't as easily opened again.
I also saw the footprint this morning outdoor next to the window. Pfffft they must kids trying to get a high. They must've worn size 6 or something.. what is our youth coming to? ...
BTW glad that it isn't as bad as you were thinking, in those occasions I'm happy to live in a small place.
