Types of conversations

I'm getting kinda bored with the game. I really wish, like the houses and items, you could have lingo and topics that have particular vibes to them. Like an item you can make have a creepy vibe or a romantic vibe. Why wouldn't they do the same with lingo? It just seems empty. Like some of my miis are talking about "going out" and I wish I could've made that a "romantic" type of lingo or topic. It seems like something that could've easily been added and make the game alot more real. I really hope this isn't all there is for the game.
