One standard exercise they ask you to do in Creative Writing Seminars is this:  What does your protagonist like?  What does he hate?

My detective kinda likes Giant Robot.  Okay.  He also hates it.  Why?  Most of his friends are into that store, that magazine.  Yeah, his ex-girlfriend gave him an Ugly Doll.  He named it.  She asked for it back.

There was a protracted custody battle.

Ugly Doll

This is how complex my detective is:  he only hates Giant Robot because, now, everybody’s jumped on the bandwagon.  But he was into it first.  He vows never to buy anything.  And then when he gets a bowl of noodles at Asahi Ramen, guess where he goes?  He never manages to leave empty-handed.

This is what he got on his last visit.  A smoking rabbit.
