Oh, does your story bring back memories. One morning I got up and immediately smelled cigarette smoke in the upstairs hall. I knew it had to be my thirteen year old daughter so I knocked on her door, checked it and sure enough, the door was locked. I told her to open the door, and after a few seconds, she did. After I entered her room, I took another few seconds looking for the cigarette because I could still smell the smoke and see it in the air. Finally I saw the smoke, coming out from under her pillow on the bed!
hahaha!
