Have you ever wondered what members of the opposite sex talk about when members of their opposite sex are out of the room?

This is question Hermione has just put to Ginny as they sat, immensely bored, in the Gryffindor common room one Saturday night.

Ginny was silent for a moment as she digested this. Then she said "What?"

Hermione started explaining it but then she stopped and closed her eyes. Somehow she had managed to confuse herself and could go no further.

"Oh screw it! What do you think boys talk about when we're not there?"

"I don't know. You would have a better idea than I would. You are best friends with two guys."

"Your brother may have taken four years to realize I was a girl but Harry noticed and I noted that he always stopped Ron when I entered the conversation, so I never found out. Haven't you ever wondered though?"

"Well, yes. Who hasn't?"

"Want to find out?" was Hermione's provocative question.

"How? We'd have to be invisible."

"We can be. Harry leant me his invisibility cloak to see if I could find a way to fix it."

"What's wrong with it?"

"Nothing. He was just tired of being able to be heard while he was under it."

"Have you fixed it?"

"No. But that doesn't stop us from using it. We could do it now. The guys are in their dorm. And we've nothing better to do."

"I agree. We should definitely do it."

Neither moved.

"Now?"

"Now."

Two minutes later the door of the girls dorm opened and closed of it's own accord.

The boy's door caused a few problems. The girls paused outside it.

"Wait. We can't just walk in. That'll be so suspicious if the door opens by itself." Ginny said thinking hard. "I know, we could make a commotion out here and then they would open the door to see what the problem is and we could sneak past them."

"Too risky. Got it!" Hermione raised her wand tip to her throat and spoke in McGonnagal's voice "Professor McGonnagal would like to see all Gryffindor's in the common room immediately please."

The girls withdrew to the far wall as the boys trooped out of their dorm and headed down the stairs. The girls took off the cloak and headed towards the door.

"Okay, let's go."

"That was an inspired touch Hermione."

"Sh! They'll be back soon. As soon as they realize it was a false alarm. Lets sit in that window seat. The one between Harry and Dean's beds. It looks like that's where the boys were nesting for the night's employment."

As they made their way across the room the door started to creak open. They dived back under the cloak and froze in place. The boys walked around them and it was a miracle they missed the girls.

The boys settled back to their games. Harry and Ron were playing Wizard Chess on Harry's bed and Dean, Seamus and Neville were playing exploding snap on Dean's.

Carefully the girls tried to make their way across the room to the window but they knocked over a table that stood in completely the wrong place. The boys looked up puzzled.

"Damn wind."

"Inside, Dean?"

"I don't know. Could be a draught. This is a castle."

"Anyway, what was McGonnagal up to? She calls us down for a meeting but when we get there the others say that she never did. Very odd."

"Never mind Harry. It was your move wasn't it?"

The girls moved across the room again and this time they reached the window without arousing suspicion.

Dean's lot were talking about the upcoming Quidditch match against Ravenclaw. Ginny listened to this one as they were talking about tactics and Ginny thought she might memorize them so she could show them all up and pretend that she came up with all of them.

Hermione gave her a hard poke in the ribs and pointed to Harry's bed.

"So, Ron, any luck with your girl yet?" Harry said winking hard at Ron.

"What's this?" Neville looked up curiously as their pack of cards blew up setting the bed alight. Dean and Seamus hastened to put it out.

"So Ron, which lady do you have your eye on this fortnight?" Seamus said winking at Dean.

"I'm not telling you. You'll laugh at me."

"No we won't."

"It can't be worse than last time. Remember? He got a crush on Pansy Parkinson!"

"No!" Ginny exclaimed and Hermione clamped her hand over her mouth with a warning look.

"Harry knows. Why don't you tell us, Harry?"

Harry looked at Ron as though asking for permission. Ron gave a small nod and assumed a resigned look. He knew that even if Harry didn't tell them they would find out anyway. Best get it over quickly.

"The girl Ron has a crush on is…"
