"Okay," Sherlock tilted his head, still looking slightly confused and curious as he watched John. As smart as he was Sherlock didn't know anything to do with social interaction, really, nevermind relationships or liking people. As a result he was pretty oblivious and luckily for John could not actually deduce his preferences in that area. It would mean that John would have to tell him. "I don't really understand... Liking people." He made a slight face. It was a general thing for him. He tolerated the relationship between Mycroft and Greg, even if he was disturbed by it. Not because they were both boys, just the whole thought of romance and them... kissing. Ugh. He didn't like seeing that kind of thing. "And yes, it certainly would be. And of course they won't catch us! If they do there is no chance of us managing to sneak out into the corridors at night." He grinned with a slight nod. Although he was sure that they would be able to choose who to go in a boat with.

(It's fine :) Do whatever you feel is best ;) Sherlock is going to be in complete denial whenever he begins to get feelings for John xD John's actually going to have to work out there's something there and convince Sherlock it could be entertaining xD)
