Converstation with First-born while walking back from Aunt's last night. The backstory: First-born is a huge Sims fan and is currently working her way throught the 'The Sims 2'.
She: "Why do they always go all blocky?"
Me: "Blocky?"
She: "Yes, blocky. You know, when they have a shower or a bath, their bits go all blocky"
Me: "..."
She: "So you can't see all of them"
Me: "Ah, yes, that would be to stop the game having an 18 certificate"
She: "What's that?"
Me: "Well, it means that the game would be for adults only"
She: "Why? Just because the Sims aren't wearing clothes"
Me: "Er, yes"
She: "But its not as if I don't know what those bits look like - we do biology, you know"
Me: (desperately trying to change the subject now) "Its just the way it is, I'm afraid"
She: "Its still silly"
Me: "Yes, I guess it is"
She: "But its one of those things I'll understand when I grow up?"
Me: "No, it probably isn't..."
