It would appear by the state of Caroline's nipples that it's pretty cold in that room. That or she had a little bit too much fun with a vacuum cleaner. I would like to make fun of her poor judgment, but that would make me a hypocrite because I too have fallen victim to the suction of the vacuum. I did not end up with puffy nips though, thankfully. There are enough odd changes happening to a pubescent boy's body that adding a cup size to my chest would not have been helping anybody. Although there was that one kid who had a bad case of gynecomastia, aka man boobs, and he was forced to take on the role of human test dummy for everyone to take turns feeling up. Oddly enough, no one thought that was an odd thing to do at the time. But that is just a basic example of the hormonal male mind for you. Just like the choices one makes in the throws of passion, it is not until it is over that one can step back and realize how strange it all was.
