I believe when you see room's window you understand the person who lives there.

Windows that have smudges, water droplets, and splattered insects all over it can easily tell you where how they feel about the window pane being clean. And sometimes some windows have their blinds closed for some privacy reasons. Some windows have screens over them so that others can filter what they see and feel. They'd rather enjoy the fresh breeze then experience the unwanted beings to cross through.
Some windows are just wide open. They don't care who sees them or who tries to get in their private home.
Heck some friends don't even have a window! It's just times like these that I'm grateful to have my window facing the west.

And so I conclude this wonderful experience to the internet. A window on my LCD monitor that I can't get enough of.
Aw that sounds so disgusting....:/
