Showing authority is the heart of handling shit tests. Nearly everything in game is based around authority/respect/admiration.

I find myself more often disagreeing and amplifying or minifying shit tests I get. It works great and brings in more diversity to your behavior. Disagreeing and minifying is just another application of amused mastery, you are treating them like they're a fun subordinate to toy with.

G: "You never want to go traveling with me"

M: "I will never leave this house! Traveling sucks, who wants to waste his time on a white beach?"

G: “Sometimes you can be such an asshole. My ex knew how to treat a lady.”

M: "No I know exactly how to treat a lady, tomorrow I will take you out to mc donalds"

G: "Do you love me?"

M: "No!, how could someone love this (point at her tits/poke her belly)"

G: "Am I important to you?"

M: "Not more than the dust under my shoes"

G: "Did you miss me?"

M: "Yea, like a hole in the head"

TL;DR: Disagree & minify/amplify works just as good as agree & amplify
