NPC Household Relationship Tests

I've made a mod to stop NPC Sims from reacting to "inappropriate" behavior (showering, cooking, etc) while your Sims are visiting. They don't react if they're good friends, family, or romantically involved. For the most part, it's worked well, but there's one problem: if there's a member of the NPC household your active Sim does not have a close relationship with, they'll still react as if your Sim is being inappropriate. Is there some way I can make it so you don't need an existing relationship with all members of the household?

So far, the tests I'm using look like this:
