The Hallway of Infinite Doorways: Melissa Smith's Bedroom

After opening the door, Jon found himself walking into a teenage girl's bedroom. He closed the door behind him and looked around the room a little, and that was when suddenly the bedroom door opened. But the strange white corridor, the one he came from, wasn't outside the room. Instead, it looked like a house's typical hallway. The girl walking into the room, he _knew_ her. She was Melissa Smith, one of the cheerleaders, and one of Sarah McMillan's friends. Jon looked around for somewhere to hide, but there was nowhere to go. He'd just have to come up with some excuse as to why he was in her bedroom. But, frankly, anything he'd think up just couldn't be adequate.
