Check your windows

Casually I enter room 330 at the aloft Montreal airport. Sprawl out on the bed for a bit. Work on some files. Then head downstairs for a late night nibble. As I stand by the elevator I glance out the window and think, wow you sure can see everything in that room. Then I realize that room is my room. Hmm, that made me think twice. Did I not notice that the room was so exposed? Should there be an alert sticker on the window?
