Conversation Tweak  

In TS4, the more ordinary conversation choices are ofter burried under object based or otherwise weird stuff. This mod makes those topics less visible and thus helps guiding your Sims the the desired conversation without endless clicks. There are several packages for you to combine to your liking. Just install the packages for choices you don't want to clutter your pie menu with. Those options will still be available in the respective category, so they aren't completely disabled.
The package LessAutonomousHuggingAndGreeting will reduce autonomous hugging and greeting. Die package LessIdleChat will limit idle chat to NPCs in unimportant roles. fewerautonomousintroductions – Sims will introduce themselves less autonomously, especially no flirty and enchanting introduction.
lessmusicalchairs – Sims will change seats less while talking.
lessrandomflirting - Prevents Sims from mindlessly flirting with everyone even though they're already in a relationship.
lessrandommean – Sims will be less mean to Sims they like.
