Sherlock

— We had nothing else to go on, until we met other children.
— Oh, yes, that was a mistake. Ghastly. What were they thinking off?
— Probably something about trying to make friends.
— Oh, yes. Friends. Of course, you go in for that sort of thing now.
— And you don't? Ever?
— If you seem slow to me, Sherlock, can you imagine what real people are like? I'm living in a world of goldfish.
— Yes, but I've been away for two years.
— So?
— Oh, I don't know, I thought perhaps you must have found yourself a... goldfish.
