Seriously need a Who the F are you option for all these random calls

If you don't know them you can reject the call. But, if you're feeling devious, you can always say yes to whatever question they have. From my experience, they're usually just asking for trouble. That's how Geoffrey Landgraab got pregnant with twins in my game. I usually tell them no or to decide for themselves. Most of the times I am like you and I don't know who either of them are. Sometimes it seems like there are too many random spam type calls in a day, especially if you play multiple sims and all of them get calls.
