I don't think that's a good idea, actually.
Or rather, I think it's an idea which would be completely impossible to implement properly.
You'll notice that Miko responds to the specifics that you mention - for example, if you select "writing or drawing", then the conversation goes on about being able to put pencil to paper and create something. There's a different between "artsy" and "intellectual".
If Lemma wanted everyone to be able to select a line of dialogue that they could actually agree with themselves, then he'd have to either provide hundreds of different answers, or make them all so non-specific that further conversation would be impossible.
I've been developing a dating game for a while now which does have a lot more options for the player - it lets you play the main character in all sorts of different ways... and it's *really difficult* to write dialogue for that kind of game that actually works. The amount of conversation you have to write increases exponentially, and even with many options, I still can't provide the ability for the player to do *everything* they'd like to.
You'll always have to roleplay a bit in dating games. It's not that bad really.
Either just select the option which is closest to what you'd say yourself, or just make up a personality and play as if you were that person. It's more fun that way.
