This title sounds more dangerous than it is. This has been happening for years. My Sims will be minding their business when someone, usually it's a sim that's older, will come through the door, doesn't matter if it's locked, and start screaming at my sim. They will shove them, slap them... they will be Sims that my household has never even met.

This honestly distresses me because Consort is beating up my in-game teenage daughter.

Does anyone know what this means? Is it because they're just grumpy sims? What is this trying to converse? Because I am NOT getting the message here.

Try to NOT use the telescope during the day. When they do, they are actually spying on their neighbors. No one likes that!
During night time, or 6pm and later, they are looking at stars.
Consort must be the first created sim in that 'Hood, or anyway, the lowest character number in your character folder.

So either you stop your sims to use the telescope from 6am to 6pm, or you can also get a mod to stop your neighbor(s) Consort or else, to ever come and slap your sims.

Sounds like you have told or had your sim look through the telescope during the day -that isn't star watching it's being a peeping tom on the sim who slapped your sim, so yeah guilty as charged and not for nothing lol. Maybe you are playing too fast, slow down and watch her as she spies and see the thought bubble she has, it will be of Consort and she will look shocked and laugh. Spying in someone's bedroom or bathroom is definitely not minding their business and is likely to get a response, sims or real life.
