D'oh

I'm sitting on my top bunk bed reading my book when there's a knock at the door. It's a little awkward opening the door from up there but there was no one else in the room and I'm too lazy to get down so, hanging on for grim life, I lean over the top of the bunk and open the door. A moments pause, then in a slightly startled tone of voice 'Uh, is *insert dorm-mate's name here* about?' The questioner, a British bloke in his early 20's or so, stares at me for a second before haltingly asking his question and looking anywhere but at me. 'No, he's not, I've not seen him for a while' 'Oh...um...ok.' Another pause 'Thanks' And he scurries off. Shrugging slightly at some people's odd behaviour I let the door close and go to push myself back up onto my bunk. This involves looking down briefly. Instantly the puzzle is solved. Today's lesson, never lean completely over a top bunk to answer the door when wearing a very strappy top unless I really, really, mean to give the person answering the door and anyone in the corridor beyond an exceptional view of my cleavage. Will I never learn?
