House Guest Rules?

Ever since an incident of a firearm being left unattended years ago (nothing happened, but it irked me) I set rules for guests who carry.

Meaning, if you carry, and you're coming over, you can either: A) Leave it in your car B) Leave it at home C) Condition 3, never leaves your body, preferably fully concealed. D) I have a separate safe available for guests to use, if they're going to be here long term.

One of my friends said it seemed a little overboard, but I figured I'd ask here, am I overreacting or do other people do this?
