In my game, 6 children from my house and 5 others from the neighbor's house ran into parent sims' private room while they were wohooing!!
An old real joke: It was my sim's wedding. I had thrown a party and invited all his friends. The only thing I forgot was the Bride herself!!!
That's gotta be embarrasing...
I have done that so many times!
I always forget the most obvious things!
And if Grimmy comes during a party where a fire is alight but the dead sim didn't die due to the fire, a dialogue box thing comes up saying:
'Oooh fire! I'll grab a sandwich and come back in a bit. I do hate reaping on an empty stomach.'
I just find that so funny
